this problem showed up recently, no work done for the generator, we made more check ,kindly find below check sequences, at the end we isolated the cross current connections, and tested the system when the VRS connected on droop mode , and the system is stable. But still did not know the root...
we have three generators cat 3412 ,800 kw at our power station, they loaded in synchronization, we have aproblem in the sharing of the reactive power KVAR.the voltage regulator used in the system model VR6, and the sharing used cross current compensation. the problem happened when disconnect any...
