Integrity Check Method of Relay Protection Data Based on Petri Net

The integrity of relay protection data is a fundamental basis for the relay protection big data platform. Aiming at the characteristics of the integrity check as multiple data types and attributes and large volume of relay protection data, this paper proposed a Petri net-based relay protection data integrity check method by taking the advantage in modeling of professional application process and resources by Petri net. The method focuses on the data requirement of relay protection professional application, searches the indispensable data for the relay protection professional application by the method of tracing based on Petri net. Accordingly, a relay protection data integrity check dataset is established, relying on this, the integrity check of the relay protection data is realized. A practical example verifies the effectiveness of this method.
