Application of Hydropower Unit Governor Islanding Control Methods in the Xiaowan Direct Current Island System

Abstract:

This paper, starting from the professional point of view of turbine governor and according to various data in the test, presents a preliminary analysis of results in combination of various tests competed after Xiaowan Power Station 700MW hydropower unit speed governor was put into island mode operation after the Chu Hui direct current line was off-stream (trial). Meanwhile, it describes the adjustment that the speed control system should make once the power system is in the island mode, including the conversion of the control mode, the switch of control parameter and optimization of control algorithm, focuses on analyzing the optimization of control strategy of the speed governor in the island mode, and discusses the active and speed adjustment method of the units and the associated performance indicators.
