Frequency Characteristics of East China Power Grid After the Operation of Huai-Hu UHV AC Transmission Demonstration Project
In view of the frequency control problem of East China Grid in the context of AC/DC interconnection,this paper presents the general principle for frequency simulation of East China Grid with reference to the actual parameter settings of online generators in East China Grid,and the real time frequency response curve in the "7.5 DC Bipolar Block Failure".Then the principle is applied in the simulation analysis of sending-end unit failure and DC blocking fault after the operation of Huai-Hu UHV AC transmission demonstration project.This research can provide supports to the planning and dispatching section in East China Grid to estimate the frequency characteristics in advance and make preparation plan for grid accidents.
