摘要
甘肃电网风电装机容量已超过水电,成为第二大能源。风电带来的电网安全稳定运行压力也随之增大。经过近年来对风电机组低电压穿越能力的检测改造,以及对风电场动态无功补偿装置的运行规范,风电场在系统发生大扰动时的稳定运行能力得到了大幅提升。为了检验风电场的抗扰动能力,在酒泉地区开展了人工短路试验,用最接近真实的手段进行了验证分析。
Wind turbine generators now have higher installed capacity than hydropower in Gansu power grid, becoming the second largest energy source. Thus, there is more pressure on the safe and steady grid operation of wind turbine generators. Through years of upgrading of low-voltage ride through capability of wind turbine generators as well as standardization of the operation of the dynamic reactive compensation device of the wind power plant, its steady operation capability has been improved greatly in the case of serious system disturbance. To test the anti-disturbance capability of the wind power plant, an artificial short circuit test is carried out in Jiuquan area, and check analysis is made in the means nearest the reality.
