基于RPC控制的光伏并网功率调节器及其控制策略
RPC Based on PV Grid-connected Power Conditioner and Its Control Strategy
摘要
Abstract
Traditional three-phase PV grid-connected device can output PV power and achieve comprehensive compensation function concurrently. But traction power supply system is a kind of special two-phase power supply system,which causes it cannot be directly used. A railway power conditioner(RPC)based on PV grid connected power conditioner and its control strategy were proposed. PV power was output and the reactive power,negative sequence and harmonic in traction power supply system were compensated comprehensively. PV power was boosted and its maximum power point was tracked by DC/DC converter. Then PV power was combined to RPC's DC capacitor. In order to ensure the balanced output current of PV system,as well as maintain RPC's comprehensive compensation function,the calculation of reference signals and the control of DC voltage was improved in proposed control strategy. Simulation model was built in Simulink and three kinds of typical working condition were taken into consideration. The simulation results verify the effectiveness of the proposed power conditioner and control strategy.关键词
