Directing against the problems appeared in digital electro-hydraulic(DEN) system of two 135 MW units in Zhoukou Longda Power Generation Co Ltd at time of severe fault occurred in the power grid
an analysis has been carried out
and solving measures being put forward
i.e.adding function of power-load imbalance judgement and function of frequency modulation control into the DEN system.The test of rejecting load for regional large power grid shows that the control system after retrofit can satisfy the requirements of stable operation in an isolated power grid.
