Abstract

The invention discloses a method of producing a power system computer aided design (PSCAD) / electromagnetic transients including DC (EMTDC) electrical power system simulation model. According to the method, power system simulator / engineering (PSS / E) format data files are used, and needed parameters to build the PSCAD / EMTDC electrical power system simulation model are extracted and calculated. Then, an electrical power network module is divided, and the parameters are used to produce automatic layout sub-network modules under the circumstance of PSCAD / EMTDC by passing through corresponding coordinates and changing algorithms. At last, auto routing is conducted among the sub-network modules and inside the modules, and building of the PSCAD / EMTDC electrical power system simulation model is achieved. According to arranged requirement of the parameters of a PSCAD / EMTDC electro-magnetic transient simulated program, the method is capable of conducting corresponding data conversion and inputting the PSCAD / EMTDC electro-magnetic transient simulated program. The produced PSCAD / EMTDC electrical power system simulation model can achieve efficient and accurate simulated analysis of the alternating current or direct current electrical power system.

Description

technical field [0001] The invention relates to the technical field of power system simulation, and more specifically, relates to a method for generating a PSCAD / EMTDC power system simulation model. Background technique [0002] High-voltage direct current transmission is a power transmission method that converts the alternating current generated by the power plant into direct current through a rectifier and transmits it to the receiving end, and then uses the inverter to convert the direct current into alternating current and sends it to the receiving end's AC grid. The high-voltage direct current transmission method does not increase the short-circuit capacity of the system, and it is convenient to realize the asynchronous network operation of the two power systems and the network connection of power systems with different frequencies, and the use of power modulation of the direct current system can improve the damping of the transmission system, suppress low-frequency osci...
