针对大规模风电接入电力系统后
传统线路保护算法难以适配系统特性变化的问题
提出一种基于时域电压推算比较的风电场送出线路保护方法。首先
基于电阻电感模型(resistor inductor based model
RL模型)构建线路电压的时域推算模型
分别求解线路中特征点的电压值。随后通过对两点电压推算结果的波形进行相关性分析
实现故障的精准识别。本文方法采用时域全量分析思路
可有效克服风电系统中撬棒动作、过渡电阻影响及风电场弱馈等特殊工况带来的干扰。为验证算法的性能
在RSCAD仿真平台搭建双馈风电场并网模型开展仿真分析
结果表明所提保护方法能够准确识别故障
验证了其有效性与适应性。
To address the issue that traditional line protection algorithms are difficult to adapt to changes in system characteristics after large-scale wind power integration into the power system
a protection method for wind farm outgoing lines based on time-domain voltage calculation and comparison is proposed. First
a time-domain calculation model of line voltage is constructed based on the resistor inductor based model
and the voltage values of characteristic points in the line are respectively solved. Then
through the correlation analysis of the waveform of the voltage calculation results at two points
the fault can be accurately identified. Adopting the time-domain full-scale analysis approach
this method can effectively overcome interference caused by special operating conditions in wind power systems
such as crowbar activation
the influence of transition resistance
and weak feed-in from wind farms. To verify its performance
a doubly-fed induction generator(DFIG) wind farm grid-connected model is built on the RSCAD simulation platform for simulation analysis. The results show that the proposed protection method can accurately identify faults
verifying its effectiveness and adaptability.
