摘要
针对动态无功补偿装置电压调节器的参数仅能在一定的短路容量范围内保持快速稳定的响应,当应用于短路容量变化范围较大的新能源汇集系统时,响应可能会变得非常慢或出现振荡.提出一种动态无功补偿装置电压调节增益自动优化方法,对应用于实际工程时电压波形畸变、电流波形畸变、其他自动电压补偿装置对短路容量计算结果的影响进行了研究并提出解决方案.在RTDS中对提出的增益自动优化方法进行了仿真研究,结果表明所设计的电压调节增益自动优化方法可以根据系统需求自动调整和优化增益.
Abstract
The parameters of the voltage regulator for dynamic reactive power compensation devices can only maintain a fast and stable response within a certain short-circuit capacity range.When the regulator is applied to large-scale new energy gathering stations,due to the wide range of system short-circuit capacity,its response may become very slow or oscillate.This article proposes a method for automatically optimizing the voltage regulation gain of dynamic reactive power compensation devices.The effects of voltage waveform distortion,current waveform distortion,and other automatic voltage compensation devices on the calculation results of short-circuit capacity in the actual engineering are analyzed and simulated and solutions are provided.A simulation study is conducted on the proposed gain automatic optimization method in RTDS,and the results show that the designed voltage regulation gain automatic optimization method can automatically adjust and optimize the gain according to system requirements.
