摘　　要：建立以抑制谐波为目标的并联电容器装置参数优化方法和数学模型,综合考虑系统谐波响应特性和主要影响因素,包括频率偏差、电抗偏差和电容偏差对系统谐波特性的影响,以及全部或部分装置投入的运行要求。优化模型以满足并联电容器装置的连续运行条件和抑制各次谐波放大为约束,以全部和部分装置投入时各次谐波放大倍数平方和最小为目标函数。运用粒子群优化算法求解优化模型,并给出了有效的实现方法。讨论了可调电抗器的应用,对工程实例进行了分析和比较。Optimization method and mathematical models on parameters of shunt capacitors in order to suppress harmonic are established based on the comprehensive consideration of power system harmonic response characteristics and the main factors influencing the harmonic characteristics including the deviation of frequency,reactance and capacitance as well as the operating requirements of all or part of the devices.The models are optimized to satisfy the continuous operation conditions of shunt capacitors and inhibit every harmonic amplification and achieve the minimum quadratic sum of the harmonic amplification multiples as objective function when all and part of devices are in operation.Particle swarm optimization（PSO） algorithm is used for solving the models and the effective solution is given.The application of adjustable reactor is discussed and the engineering cases are analyzed and compared.
