At present, the current domestic standard GB/T 26865.2 "Power System Real-time Dynamic Monitoring System Part 2.Data Transmission Protocol" and DL/T 280 "General Technical Requirements for Synchronous Phasor Measurement Devices in Power Systems" is closely related to this document. The communication protocol of the measuring device is specified in DL/T 280, and the technical requirements of the synchronous phasor measuring device are specified in DL/T 280. The three standards are used together to standardize the detection and evaluation methods of synchronous phasor measurement devices in power systems. It provides a basis and reference for the research and development, production, testing and application of measurement devices. Specification for testing of synchronous phasor measurement devices in power systems1 ScopeThis document specifies the test conditions, test items, test methods, inspection rules, test result judgment of the synchronous phasor measurement device of the power system. Determination and detection cycle. This document applies to the development, production and testing (including type testing, factory inspection and field testing) of synchronized phasor measurement devices. The development and testing of phasor measurement device products can be carried out as a reference.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document.
