摘要
介绍了一种考虑ＦＡＣＴＳ设备ＳＶＣ及故障运行方式的电力系统无功补偿优化方法，建立了以年电能损失费用与折合为等年值的新增无功补偿设备的投资费用之和最小为目标，同时考虑多种不同负荷运行方式及故障方式的数学模型，采用非线性规划中收敛性较好的共轭梯度法进行求解。算例结果表明，该方法技术上是可行的且具有较好的经济性。
A kind of optimal method for reactive power compensation planning in electrical power system considering SVC and fault condition is presented in this paper. Considering many kinds of different load operation conditions and fault conditions, the mathematical model has been established in which the sum of yearly active power loss fee and minimized investment in new addition of VAR equipment divided into each year is used as the objective function. The conjugate gradient method of non linear programming is used in the algorithm and makes the algorithm have a good convergence. The result of example systems approves that the method is feasible in technique and has obvious economic benefits.
