Abstract

The invention provides a detection method, system, device and storage medium of a phasor measurement system, wherein the method includes: loading the power grid, and loading the measurement data of a typical load day in the database to the power grid; Measure the data, set the fault scheme for each line in the power grid; according to the power grid, fault scheme and virtual measurement unit, use the phasor measurement system to test the power grid with different numbers of virtual measurement units, and obtain the fault location of the power grid; compare the faults The fault location in the scheme and the output fault location are obtained to obtain the detection result. The invention obtains the detection accuracy of the phasor measurement system and compares the advantages and disadvantages of different phasor measurement systems by comparing the fault location tested by the phasor measurement system and the fault location in the set fault scheme.

Description

technical field [0001] The invention belongs to the technical field of power grid fault detection, and in particular relates to a detection method, system, device and storage medium of a phasor measurement system. Background technique [0002] Large-scale interconnection of complex power networks requires high stability of the power system. Years of operating experience in the power system show that quickly removing faults and reducing the impact of fault currents on the system is always one of the most effective means to ensure the safe and stable operation of the power system. Due to the long operation time and complex coordination of traditional backup protection, the introduction of wide-area information into the protection system (ie wide-area protection system) can further improve the security and stability of complex power systems. [0003] The wide-area protection system can not only provide corresponding component protection, but also ensure the safe and stable oper...
