摘要
电动机群负荷和电解铝整流负荷是电力负荷的重要组成部分。根据大扰动过程中电动机群负荷对系统稳定性影响较大的特点,在河南电网濮阳供电区的中原油田进行了110kV线路三相短路故障试验。针对电解铝整流负荷的电压特性,在河南电网焦作供电区沁阳铝厂进行了调节电压的小干扰试验。介绍了河南电网人工扰动试验的方案和实施情况。由于试验过程中严格按照试验方案和预定步骤操作,上述实验没有对河南主网的安全稳定运行造成影响,获得了完整清晰的试验数据,达到了预期的试验目的。
The load of induction motor in groups and the rectification load of aluminum plant are significant components in power load. According to the feature that the load of induction motor in groups greatly affects power system stability during large-scale disturbance, a three-phase grounding fault test of 110 kV transmission line was performed at Zhongyuan Oil Field located in Puyang power supply region of Henan Power Grid. According to the voltage characteristic of rectification load for electrolytic aluminum, small disturbance test of voltage regulation was performed at Qinyang aluminum plant located in Jiaozuo power supply region of Henan Power Grid. The schemes and implementation of man-made disturbance experiments in Henan power grid are presented. These tests were strictly implemented according to the testing program and predetermined procedures, so the security and stability of the major network of Henan Power Grid are not affected, test data are complete and clear, and prospective test purposes were achieved.
