V/v接线牵引变电所负序和无功综合优化控制
Negative Sequence Current and Reactive Power Comprehensive Optimizing Control of V/v Connected Traction Substations
摘要
Abstract
When railway static power conditioners (RPC) are adopted to compensate negative sequence currents,the reactive power and harmonic currents for V/v connected traction power supply systems,in order to meet the national standard of power quality and to reduce the operating currents and losses,a negative sequence current and reactive power comprehensive optimizing control of the power quality manage system for V/v connected traction substations was proposed.The compensation mechanism of negative sequence currents and reactive power were analyzed,and the mathematical model with minimum compensating currents under the constraint of the voltage unbalance factor,power factor and device capacity was set up.For solving the multi-dimensional non-linear and constrained optimization problem,an intelligent algorithm based on the shuffled frog leaping simplified particle swarm optimization method was proposed through comparative analysis of existing optimization algorithms and the traditional analytical method.The precision,rapidity and stability of the algorithm can meet the needs for the real-time control of RPC.Engineering experimentation results were provided to illustrate that the model and its computation are effective and feasible.关键词
