Simulation Modeling Method for Substation Secondary Circuit

Abstract

The present invention discloses a transformer substation secondary circuit simulation modeling method. The method comprises the following steps: S1. according to the secondary circuit element attribute, dividing a model system of transformer substation secondary circuit simulation modeling into a three-level model that integrates a graphic with the model and directs to one specific class of elements, and establishing an element mathematical model library; and S2. instantiating the model by means of a visual editing tool, further generating a transformer substation simulation secondary circuit, and setting a library file in the element mathematical model library to an XML (Extensible Markup Language) format, wherein the visual editing tool performs compilation by using the C Language based on the QT frame. With application of the transformer substation secondary circuit simulation modeling method, establishment of the element mathematical model library is reasonable and accurate, without dependence on a certain specific simulation system, and the method has the advantages of reasonability, accuracy and versatility.

Description

technical field [0001] The invention relates to the field of simulation modeling of a secondary circuit of a power system, more specifically, the invention relates to a method for simulation modeling of a substation secondary circuit. Background technique [0002] The electrical equipment of the power system is divided into primary equipment and secondary equipment. Primary equipment is the main body of the power system, and it is the equipment that directly produces, transmits and distributes electric energy, mainly including generators, power transformers, circuit breakers, disconnectors, power buses, power cables and transmission lines. Secondary equipment is equipment that controls, regulates, protects and detects primary equipment, including control devices, relay protection and automatic devices, measuring instruments, signal devices, etc. The secondary equipment is electrically connected with the primary equipment through voltage transformers and current transformers...
