The invention discloses an intelligent substation secondary equipment logic emulation system which comprises a logic module development subsystem, an engineering building management subsystem and an engineering emulation subsystem, the logic module development subsystem is used for achieving sort management and configuration development of a module, the engineering building management subsystem is used for building emulation engineering meeting secondary equipment or a secondary system and carrying out compiling to finally generate a secondary equipment emulation engineering model capable of being used for emulation, and the engineering emulation subsystem is used for executing the secondary equipment emulation engineering and outputting an emulation monitoring result. The system can be used in an intelligent substation, the operating state of the secondary equipment and the secondary system of the whole station are simulated through system construction and logic signal emulation, the motion behavior of the secondary system and the response of the secondary system to faults or defects can be mastered through emulation operating, the successive action process in the operating process or the faults reappears, a means of mastering the characteristic of the secondary equipment and the system and a convenient secondary system training tool are provided for operating maintenance, and the technical level of substation operating maintenance and reliability of the equipment are effectively improved.
Description
technical field [0001] The invention relates to a logic simulation system for secondary equipment of an intelligent substation, belonging to the technical field of power system substation simulation. Background technique [0002] The substation is at the core of the power grid and plays an important role in power system measurement and calculation, operation monitoring, operation control, and relay protection. Carrying out substation simulation is a branch and an important direction of research in the field of power system simulation. It has the functions of research experiments, training operations, The effective means of maintenance and other functions is the operation of mathematical models and the simulation of equipment status. In terms of substation simulation research, at present, the simulation operation training of substations and the simulation research of microcomputer protection devices are relatively in-depth, but there is no simulation research on the secondary...
