摘要
近年来,环境污染问题日益突出,新能源应用得到很大的发展,打造智能、高效、可持续发展的多能互补园区是发展的趋势所在。直流配网关口变换器是多能互补园区的重要组成部分。本文通过分析直流配网架构及不同场景下变换器的拓扑结构,设计了一种基于NPP拓扑结构、电抗器-电容器-电抗器(LCL)串并联的滤波系统及SPVWM调制方法的直流配网关口变换器。介绍了此变换器的工作原理、参数计算、实现方法。最后,通过仿真试验及控保系统闭环测试证明了该实现方法的有效性。
In recent years,the issue of environmental pollution has become increasingly prominent and new energy application has developed greatly. The creation of intelligent,efficient,sustainable development of the multi-energy complementary park is the trend of development. DC distribution gateway converter is an important part of the multi-energy complementary park. In this paper,a kind of DC distribution network gateway converter is designed by based on NPP topology structure,reactor-capacitor-reactor(LCL)serial and shunt filtering system and SPVWM modulation system by way of analyzing the structure of DC distribution network and topology structure of converter at different scenarios. The working principle,parameter calculation and realization method of this converter are introduced. Finally,the effectiveness to achieve the method is verified by simulation test closed-loop test of control and protection system.
