IEC61850-based on-line leakage current monitoring equipment communication simulation method

The invention discloses an IEC61850-based on-line leakage current monitoring equipment communication simulation method, which comprises the following steps that (1) IEC61850/MMS (Manufacturing Message Specification) communication service is simulatively started; (2) the value of each analogue of certain analysis of on-line intelligent electronic leakage current monitoring equipment to be simulated, which is prestored in an SQL database, is queried; (3) an alarm rule is generated by using preconfigured telemetering limits, and corresponding alarm telesignalling states are automatically computed; (4) in the form of an IEC61850 report, each analogue and each alarm telesignalling state are transmitted; (5) the next data transmission time is waited in order to repeat the step (2) until all the prestored data are transmitted. The method can use ordinary personal computers (PC) to simulate on-line leakage current monitoring equipment to conveniently and flexibly debug and test advanced applications including the state evaluation of various backgrounds and primary equipment needing to communicate with on-line intelligent monitoring equipment in intelligent transformer substations and the like.
