ACTIVE FILTER 'l| ------ (V)-vW^ G Pulise Bridge AM GM Active Filter 5P STATCOM Based Device With Control System This applicatio n example is based on a case origi on ally created at Man itoba Hydro, in Man itoba Can ada. The problem was that farm ani mals, duri ng win ter mon ths, were experie ncing a "ti ngle voltage", due to suspected poor grounding on the local ground grid. Using PSCAD, the engineers were able to simulate the local system and determine that the grounding problem was at least partially related to ground rod resista nee. During the win ter mon ths, t he ground con ductivity is poor, result ing in a poor connection betwee n the ground rods and earth. rod While this case is running, you can adjust the ground resista nee. Notice the cha nge in voltage across the cow! Revised by J.E. Nordstrom - July 2000 三、继电保护 Case 1: -Two Thev inen Impeda nee sources conn ected via one 100km tran smissi on line.
