5高频率的功率变压器THE HIGH-FREQUENCY POWER TRANSFORMER5-0概论(INTRODUCTION)很多科学家认为磁性元件的设计是一种“高深的技术”，其实这乃是一种最重的错误观念。
磁性元件的设计乃为精密的科学，而那些所有正确的基本电磁定律，乃由以前的科学家们所研究发展出来，如Maxwell, Ampere , Oersted ,与Gauss等人。
本章主要目的就是介绍基本的磁学定律，而且为了实际的电磁元件设计，如线圈与变压器，我们将以简单的，合逻辑的，有条理的方式来深入浅出介绍磁性与电性之间存在的关系。
5-1电磁的原理（PRINCIPLES OF ELECTROMAONETISM）考虑如图5-1所示的简单电路，此由电压源V，开关S与负载L，组成一个空气线圈（air coil）的电路，如果在某些情况下，开关S被关闭（closed）,则会有电流I产生经由线上流至负载，当电流通过线圈时，就会有磁场被建立起来，如图中所示，连接于线圈之间所产生的磁场，此乃为称之为磁通量（flux）,而磁场中的磁力线可称之为磁通链(flux linkages)。
图5-1流经空气线圈的电流I会有磁通量的产生图5-2 铁磁材料棒置于线圈之内会产生较多或较强的磁通量然而，在此线圈中的磁通量并不会很大，如果我们在线圈中加入磁性材料（铁磁材料）棒，则会有额外的磁场被感应产生，因此，也就会有更多的磁通量被产生，如图5-2所示。
而磁通链将沿着磁棒前进，并经由空气传导路径形成一回路，如果铁磁铁心（ferromagnetic core ）以此种方式构成并取代了磁棒，则磁通就会呈现一连续的路径，且磁场将形成于铁心之内，因此所感应的磁场就会较强大，如图5-3所示。
图5-3 连续的铁磁性铁心会限制所有的磁通量于铁心内并有很强的磁场产生在磁场上某一点所测量的磁通聚集程度，我们称之为磁通量密度（magnetic flux density ）或是磁感应(magnetic induction),以符号B 来表示。
38ABB review 3|13Title picture Simulating the detailed electromagnetic behavior of transformers is essential for good product design.Picture perfect DAnIEl SZARy, jAnuSZ DuC, BERTRAnD POulIn, DIETRICH BOnMAnn, GöRAn ERIkSSOn, THORSTEn STEInMETZ, ABDOlHAMID SHOORy – Power transformers are among the most expensive pieces of equipment in the entire electrical power network. For this reason, great effort is expended to make the design of transformers as perfect as possible. Invaluable tools in this endeavor are simulation software packages that are based on the finite element method. Simulation software not only predicts the effects of basic physics, but it also provides a way for ABB’s century of experience in transformer design to be used in the design and exploited to the fullest. This is important as different types of transformers present different challenges in terms of magnetic flux loss mechanisms, complex nonlinear behavior and idiosyncrasies of physical design. All these factors must be accommodated while keeping computational overhead within reason.Electromagnetic simulations of transformersPicture perfect 3940ABB review 3|13mal hot spots and thus shorten the life of the transformer.Whereas resistive and eddy-current losses can be accurately calculated by 2-D simu-lation, the calculation of stray losses out-side the windings is a complex 3-D prob-lem and a suitable transformer model is necessary to solve it. This model can be created by simulation software suites that are based on the finite element method. Finite element analysis (FEA) is a sophisticated tool widely used to solve engineering problems arising from electromag-netic fields, ther-mal effects, etc. In FEA, using smaller element sizes yields higher, and thus better, resolution of the problem, but also increases the computa-tional power required, so a balance must be struck between element size, degree of model detail, approximation of material properties, computing time and the preci-sion of the results.Simulation software can resolve the basic electromagnetic field situation by solving Maxwell’s equations in a finite region of space with appropriate boundary condi-tions (current excitation and conditions at the outer boundaries of the model). How-ever, the rest of the simulation depends on the input of the user. This is where ABB’s long experience in transformer design bears fruit. Nonlinear material properties and device complexity are two significant factors that drive the computational horsepower required for the software simulation of both oil-immersed and dry-type power transformers. However, a deep knowledge of power transformer design allows very accurate simulations to be made without running up against computational limits. Power transformers have a critical task: They must step the voltage up and back down on the way from the power plant to the final consumer. In a perfect world, they would be 100 percent efficient, but in reality, every transformer generates losses. In general, the so-called load losses in transformers have three com-ponents: resistive and eddy-current loss-es that appear in windings and busbars, and stray losses that are generated in the metallic parts of transformers ex-posed to magnetic fields, eg, the tank, core clamping structures and tank shielding. This unavoidable leakage of magnetic flux not only represents a loss of energy, but can also cause local ther-An accurate calculation of stray losses and their spatial distribution requires appro-priate numerical models for the loss mechanisms in the construction materials them-selves. 1 loss distribution of the steel plate for rotation angle 45 degrees 1a Computed by resolving the interior 1b Computed by SIBC technique41the loss – a procedure that would require excessive computer power for a full 3-D simulation. Fortunately, one can employ surface impedance boundary conditions (SIBCs) to significantly reduce the solution volume and thus the computer power re-quirements. Here, the interior of the metal-lic object is removed from the computa-tional domain and the effect of eddy currents flowing close to its surface is tak-en into account by specifying analytically the surface impedance – ie, the ratio be-tween electric and magnetic fields at the surface.The usefulness of the SIBC method can be illustrated. An infinitely long steel plate with a 12 × 50 mm cross-section and skin depth of 1 mm at 50 Hz can be simulated at various rotation angles in a magnetic field. The total eddy-current loss is com-puted using a full volume resolution of the plate interior (requiring 4,220 finite ele-ments for the entire computational domain) ➔1a and an SIBC formulation (requiring 1,674 finite elements)➔1b. The SIBCyields a virtually identical loss value com-pared with the full volume case ➔2. The relative gain in using SIBC is significant even for this small object and as the size increases the relative gain is magnified.At ABB, different numerical techniques for computing loss distributions in transformer construction materials are being evaluated and improved. The objective is to find the most accurate models that can be used in 3-D simulations while keeping computa-tional overhead reasonable. This is accom-plished by combining carefully controlled experimental measurements on test ob-jects with detailed simulations. Simulating stray loss An accurate calculation of stray losses and their spatial distribution requires appropri-ate numerical models for the loss mecha-nisms in the construction materials them-selves. Losses are significant in solid materials, but also in laminated materials, such as laminated steel, since stray fields are, in general, not restricted to the plane parallel to the lamination planes. In addition to ed-dy-current loss, there is also hysteresis loss in ferromagnetic materials due to mi-croscopic energy dissipation when thematerials are subjected to oscillating mag-netic fields. Furthermore, in order to com-pute the total loss distribution accurately, the model has to take into account the nonlinearity of the magnetization curve. This nonlinearity not only influences the magnetic field distribution but also, indi-rectly, the eddy current distribution. The high degree of anisotropy in laminated steel introduces additional complications that must be taken into account.The so-called skin effect also complicates matters: Eddy currents induced close to the surface of a metallic object tend to have a shielding effect, resulting in an ex-ponential decay of fields and current to-wards the interior of the object. This skin effect becomes more pronounced as con-ductivity and permeability increase, imply-ing that, in typical materials of interest, the characteristic decay length (“skin depth”) is of the order of a millimeter or less. As a consequence, the losses are concentrated in this thin layer. At first sight, it seems nec-essary to resolve the skin depth layer into several finite elements in order to compute Picture perfect Different types of advanced numerical simulations, usually based on FEA, are applied to develop and i mprove dry-type transformer technologies and products.2 Simulated total loss in the plate as a function of rotation angle. The SIBC technique gives results very close to those obtained by resolving the entire volume.3 Geometry of the power transformer simulation model (tank not shown)42ABB review 3|13insulation and cooling of the active part are performed by ambient air. Different types of advanced numerical simula-tions, usually based on FEA, are applied to develop and improve dry-type trans-former technologies and products.TriDry – dry-type transformers with triangular wound cores In contrast to conventional transformers with planar-stacked magnetic cores, the three-core legs of the TriDry experience identical magnetic conditions ➔5. Nu-merical simulation of the magnetic fields in the core are particularly challenging because an anisotropic material model is required as the permeability is very high parallel to the laminations but much low-er in the orthogonal direction ➔5. These simulations give fundamental insight into the magnetic behavior of the TriDry transformers. Also, detailed analyses of the emitted stray field intensities of TriDry transformers can be performed by nu-merical simulations. These can be re-quired to ensure legal compliance – for example, to the 1 microtesla RMS limit for transformers installed in Switzerland in sensitive areas.to make the computational load more managable.In the initial design, where the tank shunts are too far apart and of insuffi-cient height, loss densities were signifi-cantly higher directly opposite the active part, relative to other areas of the tank ➔4a. The critical regions exposed to magnetic field impact are clearly visi-ble in the figure – mainly above and be-low the magnetic shunts. Several design iterations increased shunt height and number, and decreased spacing. The losses generated in the tank conse-quently decreased by almost 40 percent. The simulations allowed the required performance to be attained while mini-mizing the extra material, and thus costs, involved ➔4b.Electromagnetic simulations of dry-type transformers The active part (consisting of the main parts: core, windings, structural compo-nents and leads) of a dry-type transform-er is not immersed in an insulation liquid, in contrast to oil-immersed power and distribution transformers. Both electric Different suggested loss modeling tech-niques for nonlinear and/or laminatedmaterials are then evaluated based onthese results.Electromagnetic simulations ofoil-immersed power transformersThe windings in autotransformers (anABB 243 MVA single-phase 512.5/230/13.8 kV type is used here for illustration)tend to produce high amounts of strayflux relative to their physical size. Thisimplies potentially high stray losses andpossible hot spots in the transformertank. However, with appropriate simula-tion and design, a tank shielding can beproduced that avoids this. In the caseshown here, magnetic shunts mountedon the tank wall were employed asshielding. Shunts are ferromagnetic steelelements that guide the flux emanatingfrom the transformer winding ends.The 3-D FEA model included all the im-portant constructional parts necessaryto carry out the magnetic simulationsand loss calculations ➔3. Because ofthe complexity of the real transformer,some simplifications were introducedThe objective is to find the most ac-curate models that can be used in 3-D simulations while keeping computa-tional overheadreasonable.4 Influence of the tank shunt geometry on the distribution of the losses generated in the transformer tank 4a Short, spaced tank shunts give high losses (right)4b longer, closer-spaced tank shunts result in lower losses (right)43Dry-type variable-speed drive transformers Variable-speed drive transformers are used to supply AC motors. The power electronics associated with these trans-formers generate current harmonics that increase winding loss, potentially leading to hot spots. This must be taken into consideration when constructing simula-tion models. A typical example of wind-ing loss simulation is shown in ➔6. Here, the relative winding loss distribution overthe end sections of the foil conductors of the two opposite winding blocks is shown for a 12-pulse transformer with two secondary windings. The winding loss at the fundamental frequency is more uniformly distributed along the conductor surface than the winding lossof the fifth harmonic frequency. This isbecause the currents of the two second-ary windings are in phase at the funda-mental frequency, resulting mainly in axi-al flux. However, these currents are inopposing phase at the fifth harmonic fre-quency, resulting in a radial flux that con-centrates losses in the winding regionnear the axial gap between them. Thiscauses hot spots, requiring the design tobe amended accordingly.Simulation successNumerical simulation of electromagnetic fields have proven to be a very powerful tool in the development and design of to-day’s transformers. Appropriate numeri-cal models facilitate, for instance, the simulation of stray losses in structural components, winding losses or core magnetization – applicable to different types of transformers.The numerical simulations described here are used in research, development and engineering by ABB and they make a significant contribution to ABB’s high-quality oil-immersed and dry-type trans-former products.Daniel Szary janusz Duc ABB Corporate Research Kraków, Poland *******************.com *****************.com Bertrand Poulin ABB Power Products, Transformers Varennes, Quebec, Canada ************************.com Dietrich Bonmann ABB Power Products, Transformers Bad Honnef, Germany ***********************.com Göran Eriksson ABB Corporate Research Västerås, Sweden ***********************.com Thorsten Steinmetz Abdolhamid Shoory ABB Corporate Research Baden-Dättwil, Switzerland *************************.com ************************.comSurface imped-ance boundary conditions (SIBCs) can significantly reduce the solu-tion volume and thus the computer power require-ments.Picture perfect 6 Electromagnetic simulations of a 12-pulse transformer; winding loss distribution over the end sections of the foil conductors6a At the fundamental frequency 6b At the fifth harmonic frequency 5 TriDry transformer and the simulated magnetic flux density distribution in its magnetic core.5a TriDry transformer 5b Magnetic flux density distribution。
