Logic simulation method of comprehensive automation system equipment of transformer substation

Abstract

The invention discloses a logic simulation method of the comprehensive automation system equipment of a transformer substation. The logic simulation method comprises the following steps: equipment configuration module development, simulation module library management, simulation engineering configuration / management, simulation configuration rule examination, simulation compiling, simulation operation control, simulation energizing control and simulation monitoring. The comprehensive automation system in the transformer substation is subjected to the logic function decoupling of equipment according to a three-layer structure, forms a simulation module library capable of reconfiguring logics and implementation functions, constructs and generates a simulation target system, which is the same with a practical transformer substation, of a secondary system by construction modules, applies or imports an energizing quantity to carry out simulation operation and carries out whole-process simulation monitoring, wherein the three-layer structure comprises a station control layer, a spacing layer and a process layer. The method is favorable for quickly mastering working principles in the secondary system and equipment of the transformer substation and mastering relevant overhauling and maintaining skills, and provides a means for accident analysis and processing.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a logic simulation method for substation integrated automation system equipment. Background technique [0002] The substation, as the key link in each link of power grid generation, transmission, transformation, distribution, utilization, and regulation, undertakes the important role of power system measurement and calculation, operation monitoring, operation control, and relay protection. The acquisition source and command execution unit are at the core of the power grid. Their normal operation and correct work are crucial to ensure the safe, stable, reliable and economical operation of the power system. The stable and reliable operation of the relay protection system in the substation, as well as the operation and maintenance level of the operation and maintenance personnel, directly affect the reliable operation of the substation. [0003] With the development of smar...
