DETECTION METHOD AND SYSTEM OF INTELLIGENT RELAY PROTECTION DEVICE

摘要

Aiming at the ineffective detection of the dynamic performance of a relay protection device in an intelligent substation, based on the feature of the digitalization and informatization share of an intelligent substation secondary system, a detection method and system of an intelligent relay protection device provide a detection method which regards a digital simulation system as a data source and regards the synchronous work of a plurality of digitized relay protection testers as a detection means and structures a detection system of the intelligent relay protection device. In a lab, simulation models can be constructed according to the actual electric topological structure of the intelligent substation and device parameters, a plurality of operation situations which probably happen in a transformer substation can be simulated, transient test data which have higher similarity with the actual operation situations can be acquired by simulation calculation and transformation, the transient test data can be output in a playback mode in the intelligent substation, and the dynamic performance detection of the relay protection device and the checkout of protection setting values can be carried out.
