Abstract

The invention discloses a comprehensive analysis method and system for micro synchronous phasor measurement, and the method comprises the steps: evaluating the availability and rationality of each [mu] PMU measurement, evaluating the reliability of a single [mu] PMU measurement based on the availability and rationality evaluation results, and evaluating the reliability of a single [mu] PMU measurement based on the reliability evaluation result of the single [mu] PMU measurement. Reliability of plant station [mu] PMU measurement and reliability of system [mu] PMU measurement are evaluated, andcomprehensive analysis and evaluation of [mu] PMU measurement are realized.

Description

technical field [0001] The invention relates to a comprehensive analysis method and system for micro-synchrophasor measurement and measurement, and belongs to the technical field of intelligent analysis and control of power systems. Background technique [0002] The synchrophasor measurement technology based on Global Positioning System (GPS) technology has taken a new step in the distribution network, realizing the dynamic synchronous monitoring of the power grid in a wide area, and extending the scope of dispatch monitoring from steady state to dynamic. The distribution network wide-area measurement system consists of micro-synchrophasor measurement (hereinafter referred to as: μPMU), dispatching master station and high-speed data communication network distributed in the station section. Through geographically distributed μPMU, different electrical points in the power grid are collected synchronously. Phasor (voltage, current, etc.), analog quantities (power, frequency, et...
