同步相量测量技术在配电网中的应用

随着智能电网建设的不断深入,配电网的智能化升级改造也步入正轨。同步相量测量技术不仅适用于输电系统,在实现配电网智能化方面也能发挥积极作用。基于美国FNET系统和国内WAMS Light系统,给出国内外配电网同步相量测量系统概念;从状态估计、故障定位、谐波估计、孤岛检测角度,介绍同步相量测量技术在配电网诊断方面的应用,并从微电网协调、电能质量控制、控制与保护角度论及它在配电网保护方面的应用。最终,针对配电网同步相量测量技术发展所遇问题,试着提出明确的解决思路。

Applications of synchronized phasor measurement technology in distribution systems

With the development of smart grid construction , the smart distribution system is also constantly upgrading . The synchronized phasor measurement technology not only applies to transmission system , it also plays an active role in achieving smart distribution system .This paper introduces the concept of synchronized phasor measurement system in distribution system based on American FNET system and domestic WAMS Light system .Then, a review on diagnos-tic applications of synchronized phasor measurement technology in distribution system is presented from the following aspects:state estimation , fault location , harmonic estimation and island detection .Meanwhile , a review on control ap-plications of synchronized phasor measurement technology is presented from following aspects : micro-grid coordina-tion, power quality control , control and protection .Finally, some solutions are proposed to deal with problems en-countered in the development of synchronized phasor measurement technology .
