Abstract
Based on analysis of AGC orders and feedback data during an UHVDC block fault accident treatment,abnormal conditions in automatic generation control system are discussed and rectification measures are proposed.Automatic generation control (AGC) strategies in Zhejiang power grid and accident treatment of one ±800 kV Yibin-Jinhua DC unipolar block fault performed by provincial dispatcher are introduced.System defects are found after reviewing data changes.Improvement measures in transmission mechanism of power importing data,control of low frequency and dynamic dead band optimization are proposed.These measures are already operated in actual power grid system operation which have instructive significance for UHVDC export/import power grid.关键词
