英文摘要： The development and extension of micro-grid can help promote distributed generation and renewable energy to access to in large, meet the load demand at a highly reliable level, implement active distribution network effectively, and accelerate the transition of traditional distribution network to smart grid. The research on micro-grid technologies, micro-grid project, and the development of new equipment will entirely be implemented by micro-grid real time simulation platform. Because of good performance in economy and scalability, the digital real time simulation of micro-grid will be preferred in micro-grid research and construction. Considering the characteristics of distributed power generation systems, the decoupling methods of micro-grid and numerical stability issues are involved in the project. The solutions for the action of non-simulation points in micro-grid switching element and numerical simulation oscillation will be solved by the inherent parallel architecture of FPGA; the optimal design of specialized high-speed arithmetic and the interconnection problems of arithmetic units will be solved by the design idea of DSP; with the dynamic reconfiguration technology of FPGA, it will be efficient to study the rational use of FPGA resources and its reliability. The simulation problems about micro-grid dense structure and large numbers of micro-grid power electronics will be solved in this project, and the emulator will be granted with high qualities in scalability, economy and self-healing, which provides a theoretic guidance for the real-time simulation platform of micro grid, smart distribution network.
