风电场接入对电网稳态特性的影响研究
|
摘要
分析了风电场在电力系统计算中的稳态等值方法,以某地区实际电网为例,研究了大型风电场对稳态特性的影响规律。研究表明,风电场的无功补偿主要是补偿各级升压变压器的无功损耗,宜在风电场集中接入点安装无功补偿设备进行集中补偿,但投切低压电容器和有载调压(OLTC)变压器的电压调整特性不如静止无功发生器(SVG),不适合作风电场的主要调压措施。
The steady equivalent methods of wind farms in power system calculation are analyzed.The influence of wind farms on steady characteristics are studied with the actual power grid in China.The research results show that the reactive power compensation of the wind farm is mainly to compensate for the reactive power loss at all levels,and it should be installed in the centralized access point of the wind farm,but the voltage adjustment characteristic of the low voltage capacitor and on load tap changer(OLTC)transformer is not as good as the static var generator(SVG).
