Simulation protection measurement and control apparatus

Abstract

The invention relates to a simulation protection measurement and control apparatus. The simulation protection measurement and control apparatus includes a programmable chip, an operation interface, acommunication module and a power supply module, wherein a program for simulating a field protection device or a measurement and control device based on code table information is run in the programmable chip, so that a function of reporting the remote measurement amount, remote signal amount, and soft messages of the field protection device or the measurement and control device can be simulated andrealized; the operation interface is in communicated connection with the programmable chip so as to input an instruction to the programmable chip to control the verification process; and the communication module is connected to the programmable chip to import the code table information into the communication module, report the information to the superior monitoring and control module, or receivethe instruction sent from the superior monitoring and control module and send the instruction to the programmable chip. The simulation protection measurement and control apparatus can replace the actual field protection device or measurement and control device to complete function verification of the superior monitoring and control module, can avoid the influence of the verification process on thepower grid, can improve the verification efficiency, and can reduce the verification workload.

Description

technical field [0001] The invention belongs to the field of power system substation automation, and in particular relates to an analog protection, measurement and control device for simulating an on-site protection device or a measurement and control device in a substation and applied to the function verification of a superior monitoring and control module. Background technique [0002] The verification of various signals of on-site protection devices and measurement and control devices in substations generally adopts the method of on-site actual verification. When the upper-level monitoring and control modules such as the telecontrol database, background machine, and monitoring master station change, the signals often need to be re-verified. At this time, the traditional verification method needs to cut off the power of the actual power equipment to be verified, and then use the method of inputting analog current and voltage for verification. This verification method requi...

Problems solved by technology

[0005] (1) The equipment must be verified by power failure, which is inefficient and requires power failure verification for each device;

[0006] (2) During the acceptance process, equipment such as circuit breakers, protection measurement and control devices need to withstand the amount of faults, and make corresponding actions and feedbacks frequently, which has a great impact on the life of the equipment, especially the life of the primary equipment. The impact on the equipment is particularly large, affecting the operation safety of the equipment;

The burden of personnel planning is heavy and the workload is heavy
