Optimization Control Strategy Analysis of Local Power Grid Reactive Power
摘要
Abstract
The 220 kV switching station and Guoao double circuit lines owned by Inner Mongolia International Cooperation Co.,Ltd. assume the Mongolian Oyu Tolgoi (OT) power transmission project tasks. Calculate power flow for Guoao double-circuit lines on a variety of operating modes to analyze power supply capacity of Guoao double circuit lines under different operating voltages and loads. For Guohe switching station′ s low operating power factor under condition of low load on the OT side, analyzed from the grid voltage, OT side load size, power factor, compensation capacity, etc., according to size of load on OT side. Proposed phased control strategy to control load power factor of OT side, that was, when the lower load on OT side, by controlling the power factor of OT side, absorbed partial reactive power produced by line charging power. By calculation, verified the feasibility and economy of the strategy.关键词
