摘要
分布式发电因其投资省、发电方式灵活、与环境兼容等特点,日益普遍地与大电网联合运行,给现代电力系统运行与控制带来巨大的变化。大力发展分布式发电技术将是电力系统未来发展的必然趋势。因此,研究分布式发电具有重要的理论意义和重大的应用价值。概述了国内外分布式发电的发展现状及应用前景,简要介绍了分布式发电的概念及几种新型分布式发电技术,分析了分布式发电并网系统及分布式发电并网对电力系统规划、电能质量、继电保护、可靠性等方面的影响,最后对分布式发电的未来研究方向和需要进一步研究的问题作了展望。
The distributed generation (DG) possesses the following advantages: saving investment, flexibility and compatibility. The joint operation of DG with power grid brings tremendous variation in control and operation for modern power system. The current situations of distributed generation at home and overseas are reviewed. Concepts of DG and some new types of DG are introduced. The effects of DG grid interconnection system on power system are analyzed, such as power system planning, power quality, protection and the reliability. The development trend of DG study and some future problems are discussed.
