Method and device for preventing faulty operation of electric power system based on wireless communication

Abstract

A method for preventing faulty operation of an electric power system based on wireless communication comprises a fault-preventing host machine, at least one fault-preventing lock and a lock controller connected to the fault-preventing lock by a communication cable. The fault-preventing host machine is provided with a main control module, a first communication module and a logic check module. The lock controller is provided with a second communication module and a control module. The first communication module and the second communication module realize the data transmission of the fault-preventing host machine and the lock controller. Compared with the prior art, the lock controller and the fault-preventing host machine of the invention realize the data transmission by using a Zigbee wireless communication network. The lock controller can directly control opening and closing of the lock, so the operation of opening and closing the lock can be performed without manual intervention. Thelock controller real-time acquires the spot state of the lock and device and feeds back to the fault-preventing host machine, for ensuring the proper operation of device and lock and promoting the reliability and the safety of the spot operation.

Description

technical field [0001] The invention relates to a method and device for preventing misoperation in a power system substation. The anti-misoperation device adopts a wireless communication method to realize the safety maintenance of electrical equipment and effectively prevent misoperation. Background technique [0002] Existing electrical misoperation refers to behaviors that violate normal operating procedures caused by various reasons, mainly including wrongly closing the circuit breaker, closing the isolating switch with load, hanging the ground wire with electricity or closing the knife switch with electricity, with ground wire or Misoperation of electrical equipment is extremely harmful, such as grounding knife switch closing, non-synchronous paralleling, etc., which may cause damage to substation equipment, large-scale power outages, and even personal casualties. Therefore, preventing electrical misoperation accidents is an important aspect of power safety production im...

Problems solved by technology

However, the state acquisition device in this patent is installed on the remote control, and the operator needs to carry the mechanical key and the remote control at the same time, and the lock can be opened or closed only through the combination of the remote control and the mechanical key, and the operation is relatively complicated; and , the status acquisition of the above patent is not real-time online, that is, the status of the device can only be known when it is in operation. If the device changes position when it is not in operation (such as when the switch trips), the error prevention host will not be able to obtain this status, and there will still be problems due to the status of the device and Misoperation accidents caused by unresponsiveness on site; in addition, the operation of the lock in this patent requires manual intervention, and the staff can only operate the knife switch by inserting the mechanical key into the lock head, which is highly dependent on manual labor and difficult to achieve Automation, on-site work efficiency is low, and manual entry into the site operation also has certain dangers
