摘 要
高压直流配电网是近年来兴起的一种新型配电网，它以其高效节能、适应能力强、便于智能化控制等优点而备受关注。但目前仍存在着标准化不完善、直流供电可靠性不高、故障处置费用高昂等问题，制约了该系统的安全与控制。因此，本项目拟从 LDC配电网的特性及控制策略的理论依据入手，对其面临的主要问题进行分析，并从策略优化、接口自适应、控制和安全性三个方面展开研究。为此，本项目拟从控制策略的选取与分析、控制算法的设计与仿真、控制系统的硬件实现三个层面展开研究，最终形成一套适用于低压直流配电网的快速控制算法。研究成果将有助于提升 HVDC配电网的输电效率与稳定运行，为其大规模推广应用奠定理论与技术支撑。

Abstract
Low-voltage DC power distribution system, as a new type of power distribution, has many merits such as high efficiency, energy-saving, adaptability and intelligence. But because the standard is not perfect, the DC power is not reliable, and the trouble shooting is very high, so the control and security of the low voltage DC power distribution system is confronted with some challenges. Based on the analysis of the existing problems of low voltage DC distribution system, three possible strategies are proposed: strategy optimization, interface adaptation, control and safety. In order to solve these problems, this paper researches the choice and analysis of the control strategy, the design of the control algorithm and the simulation, the hardware realization of the control system. It is proved that the study can improve the transmission efficiency and the running stability of the low voltage DC distribution system, and provide the theory foundation and technique method for the widespread use of the low voltage DC distribution system.
