摘要
运行中的交流滤波器组一旦出现不平衡电流超标,需要调整交流滤波器组组合方案时,按传统的高试调整方法,检修工作量大,且不确定性高。利用Matlab仿真软件,结合德阳换流站运行检修实际,提出一种新的交流滤波器组不平衡电流调整策略。新策略根据现场实测数据构建数学模型,利用穷举的原理和Matlab软件进行仿真优化,调整后的高压电容器组,利用现场试验测定其桥臂间的不平衡电流,验证仿真优化结果的可靠性。根据仿真分析和现场试验的结果来看,新方法理论思路正确,达到了提高工作效率的目的。
When the unbalanced current of the operating AC filter is larger than the standard one,it is necessary to adjust the AC filter combination scheme.Based on the traditional high-voltage test adjusting method,the workload is heavy and the uncertainty of the result is high.This paper proposes a new unbalanced current adjusting strategy of AC filter using Matlab software and the measured data of Deyang Converter Station.The new strategy sets up a mathematical model using the measured data on spot and makes use of the infinitude-substitution principle and Matlab software to carry out the software simulated optimization,then uses the field test to measure the unbalanced current between bridge arms of adjusted HV capacitor banks,and validate the result of the simulated optimization.The results of simulated optimization and field test show that this new method is correct and achieves the purpose of improving efficiency.
