电力系统同步相量测量单元(PMU)应用和维护

Synchronized phasor measurement unit(PMU) application and maintenance

随着经济的快速发展,电力需求不断提升,电网已进入"特高压互联、大电网、大电源"的发展阶段。为了提高电网的动态监视水平,保证电网安全稳定运行,本文提出切实提升同步相量测量单元PMU装置的稳定性和可靠性,对电力系统同步相量测量单元(PMU)时钟的维护和设备的日常维护巡视,并提出充分利用同步相量测量单元PMU动态数据的特点,发挥同步相量测量单元PMU的作用。

With the rapid economic development, electricity demand is rising, the grid has entered the stage of 'ultra high voltage,large power grid interconnection, big power'.In order to improve the level of power system dynamic monitoring,ensure the safe and stable operation of power grid,this paper improve the synchronous phasor measurement unit PMU device stability and reliability of the power system, the synchronous phasor measurement unit(PMU) of daily maintenance and equipment clock patrol,and make full use of the characteristics of synchronized phasor measurement unit PMU data the synchronous phasor measurement unit, play the role of PMU.
