Abstract

The invention discloses a synchronized phasor measurement method for multi-level real-time verification. Firstly, the target signal in the power grid is obtained, and then the target signal is verified in real time to distinguish the transient mode, steady-state mode and dynamic mode of the power grid. Transient mode, steady state mode and dynamic mode use adaptive transient algorithm, steady state algorithm and dynamic algorithm to measure the synchronized phasor of the power grid, and can adopt adaptive algorithm for three different modes in the power grid, because Each mode uses an appropriate algorithm, so it can meet the requirements of response speed and measurement accuracy when measuring the synchronized phasor of the power grid. Compared with using one measurement algorithm in three different modes in the prior art, when measuring synchronized phasors in three different modes of the power grid, both the measurement accuracy requirements and the response speed requirements can be guaranteed. The invention also provides a synchronized phasor measurement device, equipment and storage medium for multi-level real-time calibration, with the above effect.

Description

technical field [0001] The invention relates to the technical field of automatic measurement of power systems, in particular to a multi-level real-time calibration synchronized phasor measurement method, device, equipment and storage medium. Background technique [0002] The connection of large-scale distributed power and electric vehicles to the power grid has greatly increased the complexity and insecurity of the power grid. In order to meet the requirements of real-time monitoring, fault diagnosis and rapid control of the power grid, it is necessary to perform a Measurement. When measuring the synchronized phasor of the power grid, a synchronized phasor measuring device is used. [0003] The synchrophasor measurement algorithm is the core of the synchrophasor measurement device, and the performance of the synchrophasor measurement algorithm directly affects the accuracy of the state estimation, fault diagnosis and location of the power grid, and the coordinated control o...
