Short circuit parameter measuring instrument master-slave collaborative sampling method, system and device and storage medium

Abstract

The invention discloses a master-slave collaborative sampling method, system and equipment for a short-circuit parameter measuring instrument and a storage medium, and relates to the technical field of automation and measurement of a power system, and the method comprises the steps: building a short-circuit parameter measuring system based on a three-layer master-slave architecture, and carrying out the initialization of the short-circuit parameter measuring system; sampling tasks are formulated and distributed through a master node according to power distribution network conditions and measurement requirements, and slave nodes perform synchronous sampling according to the tasks and dynamically adjust parameters; the slave nodes transmit compressed data according to data characteristics, and a receiver decompresses the compressed data and performs distributed processing to obtain an intermediate result; receiving the intermediate result through the main node to complete multi-stage data fusion, calculating a short-circuit parameter matrix and evaluating the result; the problems of poor time synchronization and low data acquisition and processing efficiency of a traditional method are solved, the measurement accuracy and efficiency are improved through the steps of establishing a unified time base, reasonably distributing tasks and the like, the stability and reliability of the system are guaranteed, and the output result provides support for operation management of the power distribution network.
