Remote starting device for black-start diesel generator

Abstract

According to the remote starting device for the black-start diesel generator, the LORA local area network communication module is used for remotely transmitting an instruction to the receiving deviceof the dam crest diesel generator, and the receiving device obtains the starting instruction of the diesel generator through LORA, controls the relay to act and is connected into a normally open contact of a diesel generator starting control system to be closed; the diesel generator starts an operation process and automatically builds up voltage to rated voltage, a worker presses down a diesel generator outlet switch closing button in the sending device, a normally open contact of a diesel generator outlet switch closing channel connected to the receiving device is controlled to be closed, a diesel generator outlet switch is closed, a station service system restores power supply, the black start starting process is continuously executed, and the sending device remotely controls the receiving device, so that inconvenience caused by field operation of workers is avoided, and the whole black-start time is shortened.

Description

technical field [0001] The invention belongs to the technical field of black start, and in particular relates to a remote start device and method for a black start diesel generator. Background technique [0002] When a power outage occurs in the power grid, units capable of black start in the grid are needed to help it restore power supply, supply power to important loads in time, and minimize the impact on society. Diesel generators are very important for units that do not have self-storage start-up capabilities, or for units whose self-storage is not enough to maintain normal startup The backup power supply is also the emergency power supply for the floodgate on the dam crest, to ensure that the floodgate can be lifted smoothly in the event of a flood and the normal working power supply is lost, ensuring the safety of the dam. Black-start diesel generators are usually installed on the top of the dam, which is far away from the main powerhouse. The main reason for installi...

Problems solved by technology

Black-start diesel generators are usually installed on the top of the dam, which is far away from the main powerhouse. The main reason for installing them on the top of the dam is to prevent the diesel generators, which are used as life-saving work of the power station, from being unable to work normally due to flooding and causing black-start The need to restore the power supply of the power system of the plant by the diesel generator has brought a lot of inconvenience. The staff need to go to the top of the dam to operate. The distance to the top of the dam is usually not short. It is time-consuming and laborious to start the diesel generator once, which is not conducive to the quick start of the unit Sent request, taking up limited recovery time
