8月31日9时25分,东北电网在赤峰大唐东山风电场进行了验证风电机组电压穿越能力的人工短路试验,并获得圆满成功。近年来由于风电的快速发展,风电已成为东北电网仅次于火电的第二大电源。因风电大多集中接入220千伏高压电网,其低电压穿越能力问题已成为影响系统安全最为重要的因素。虽然国家已出台风 At 9:25 on August 31, Dongbei Power Grid conducted a manual short-circuit test to verify the voltage ride-through capability of wind turbines at Datang’s Dongshan Wind Farm in Chifeng and achieved complete success. In recent years due to the rapid development of wind power, wind power has become the second largest power source of the Northeast Power Grid, second only to thermal power. Due to the fact that wind power mostly concentrates on the 220 kV high-voltage power grid, the problem of low voltage ride-through capability has become the most important factor affecting system safety. Although the country has a typhoon
