Transformer station equipment function association database establishing method and event association information group filtering method

Abstract

The invention discloses a transformer station equipment function association database establishing method and an event association information group filtering method. The transformer station equipment function association database establishing method comprises the following steps: establishing a transformer station equipment function association model, establishing a transformer station equipment function association database template, parsing an SSD file, parsing an SCD file, and establishing an instantiated equipment function association database by using the transformer station equipment function association database template and the equipment information obtained from the SSD and SCD; and the event association information group filtering method comprises the following steps: capturing the state quantity displacement information of GOOSE network message and MMS network message, and filtering the network messages by using information association relationship determined by the station equipment function association database in order to obtain an event association information group. The transformer station equipment function association database is used to realize information filtration, all information serving for transformer station secondary equipment function analysis is rapidly extracted, and the information is displayed together with a graph for describing the function relation in order to provide direct help for rapid decision of scheduling personnel.

Description

technical field [0001] The present invention relates to the field of intelligent substation equipment information extraction and display, and in particular to a method for establishing a substation equipment function association library based on functional association relationships, and based on this, realizes events that serve the intelligent substation function execution correctness judgment and equipment defect analysis Association information group filtering method. Background technique [0002] Substations are an important part of the smart grid. In addition to completing functions such as information collection and measurement, control, protection, and metering, intelligent devices in substations should also support functions such as analysis, decision-making, and automatic control of dispatching operations. [0003] The realization of substation functions depends on the process of issuing, transmitting and executing commands (information). In a smart substation, inf...

Problems solved by technology

Since the current information display method does not organize information related to functions, it is difficult to evaluate the ability of secondary equipment to perform functions and the integrity of the process of realizing functions, which brings difficulties in analyzing equipment defects and hidden dangers of secondary system functions. Such an information utilization method is difficult to reflect the technical advantages of smart substations
