IEC (International Electrotechnical Commission) 61968-based power distribution network model interoperation and functional verification method

Abstract

The invention discloses an IEC (International Electrotechnical Commission) 61968-based power distribution network model interoperation and functional verification method. The method comprises the following steps of: a) modeling for the power distribution network IEC61968 standard through the primary equipment and the secondary equipment; b) implementing a communication function with a power distribution network main station through the transmission protocol of the 5-104 parts of the standards of power industry of the People's Republic of China; c) simulating the reporting abnormal conditions of the secondary equipment information; d) simulating the simulation run of the power distribution network, wherein an FTU (Feeder Terminal Unit) performs protection simulation, a switch performs reclosing simulation, a simulation pool finishes typical load curve edition and running management, and a simulation algorithm is responsible for overall running schedule of the power distribution network model, and analogue simulation of actual running state of the power distribution network; e) simulating fault and exception test scenes; f) testing terminal access capacity. The method provided by the invention is used for simulating the power distribution network in practical applications so as to improve the construction efficiency of the power distribution network and reduce the investment cost.

Description

technical field [0001] The invention belongs to the technical field of power systems, in particular to an IEC61968-based distribution network model interoperability method. Background technique [0002] With the development of my country's urban and rural power grid transformation, the requirements for power distribution management systems have become increasingly urgent. The information interface of the power distribution management system involves a wide range of areas, and a unified interface specification needs to be defined. The International Electrotechnical Commission has formulated the IEC 61968 series of international standards, which define the integration interface between various applications of the power distribution management system, and provide the possibility of information integration between the legacy or newly-built application software of power companies or different software providers. The problem with the installation and access of the distribution ne...
