摘要
分布式发电作为市政电网系统的重要补充,是未来可再生能源利用的一种新形式,微电网中心控制器是分布式发电与市政电网联合给负载供电的一种核心控制装置。本文研究了微电网中心控制器的工作原理,并对控制器的系统结构进行了设计。控制器的控制单元采用TMS320F28338型DSP芯片,对逆变电路的智能功率模块PM75RLA120进行了控制实验,实验结果表明,采用所提出的设计方案可以实现对微电网中心控制器输出电压波形和电流波形的良好控制。
Distributed generation as an important supplement of the municipal power grid, which is a new form of renewable energy in the future, micro-grid central controller is a core control device that distributed generation and municipal power grid joint to power the load. This paper studies the works of the micro-grid central controller, and designs the system architecture of the controller. The control unit of the controller adopt TMS320F28338-DSP chip, the control experiments on the intelligent power module of the inverter circuit PM75RLA 120. Experimental results show that the proposed design scheme can achieve good control of the micro-grid central controller output voltage waveform and current waveform.
