Intelligent control system for unattended substation

Abstract

The invention discloses an intelligent control system for an unattended substation. The system comprises a transformer and a ventilation system, the ventilation system is used for reducing the temperature of the transformer, the ventilation system comprises an air draft subsystem, an air induction subsystem and a controller, the controller is connected with the air draft subsystem and the air induction subsystem, the controller is used for detecting and controlling the air draft subsystem and the air induction subsystem, and the controller is used for detecting the temperature of the transformer and parameters of a ventilation motor, controlling whether the ventilation motor is started or not according to a detection result, detecting the parameters of the ventilation motor after the ventilation motor is started, and determining whether the ventilation motor is abnormal or not. The outlet of an air inducing channel is connected to the inlet of an induced draft fan, and the outlet of the induced draft fan directly faces a transformer heat dissipation device, so that efficient cooling of the transformer is achieved; by detecting various parameters of the ventilation motor, the state of the ventilation motor is monitored in real time, the normal performance of the ventilation motor is ensured, and intelligent control over the transformer substation is achieved.

Description

technical field [0001] The invention relates to the technical field of substation control, in particular to an intelligent control system for an unattended substation. Background technique [0002] At present, there are more and more unattended substations, and the intelligent control of unattended substations is becoming more and more perfect, but at present they all focus on the intelligent control of transformer parameters. However, the current ventilation system of substations has direct air channels Entering the transformer room, the ventilation equipment will directly exhaust the room from the roof. In this way, the air entering the transformer room directly flows out from the roof, and the part passing through the transformer is very small, which cannot cool the transformer well, and the cooling effect is not ideal. The exhaust motor is only controlled on or off. When the room temperature of the transformer exceeds the set value, an alarm occurs. When the room tempera...

[0002] At present, there are more and more unattended substations, and the intelligent control of unattended substations is becoming more and more perfect, but at present they all focus on the intelligent control of transformer parameters. However, the current ventilation system of substations has direct air channels Entering the transformer room, the ventilation equipment will directly exhaust the room from the roof. In this way, the air entering the transformer room directly flows out from the roof, and the part passing through the transformer is very small, which cannot cool the transformer well, and the cooling effect is not ideal. The exhaust motor is only controlled to be on or off. When the room temperature of the transformer exceeds the set value, an alarm will be generated. When the room temperature is high, the switch will be turned on to allow the exhaust motor to work. When the room temperature meets the requirements, the switch will be turned off to stop the exhaust motor.
