Design Of Intelligent Control System For High Voltage Substation Auxiliary Equipment

With the gradual development of smart cities and smart technologies,urban electricity consumption is increasing day by day.Therefore,the construction of power grid plays a crucial role in electric power transportation.As a key hub in the power grid,substation is the foundation of the construction of the whole power grid,and also the key link to ensure the sustainable operation of the whole power grid.However,at present,there are still many domestic substations in the traditional mode of operation and maintenance,the monitoring and control of environmental data always need manual intervention,the processing of monitoring data is relatively weak,so that under the long-term work,not only makes the substation aging problem is serious,but also will appear to endanger the safety of personnel and equipment.Aiming at the traditional environmental monitoring mode of substation,this paper proposes a set of intelligent control system of auxiliary equipment to improve the shortcomings of the traditional environmental monitoring of substation.Combining environmental data monitoring and auxiliary equipment management,it has the advantages of real-time monitoring,accurate data,stable control,simple operation,and strong extensibility in the later stage of the overall design.Effectively improve substation automation and intelligent level.In this design,according to the specific needs of the actual project,according to the environmental temperature and humidity and liquid level height and other variables for data acquisition and corresponding auxiliary equipment control,to achieve the remote control in personnel monitoring and unattended automatic control two main functions.The intelligent control system adopts modular design as a whole.Digital sensor and ultrasonic liquid level meter are used to obtain data at the environmental monitoring end.The processed data is transmitted to the station network monitoring platform and substation data cloud platform through the Intranet.At the control end of auxiliary equipment,the dehumidifier and water pump are controlled by infrared remote control of air conditioning and relay protection,which can be controlled remotely through internal instructions or automatic monitoring of equipment.After the design of all modules is completed,function debugging and overall performance test of each module are carried out,and appropriate improvement is made for the function of each module.On the basis of the above work,the intelligent measurement and control terminal is applied in the field test experiment of substation,connected with the Intranet of substation,tested the communication function of equipment,and verified the remote control ability and automatic control ability of the whole system.The experimental results show that the intelligent system of auxiliary equipment developed in this paper can realize the real-time monitoring of environmental conditions,and at the same time manage the auxiliary equipment in the substation in a unified way.The overall data collection accuracy of the equipment is high,it can effectively control the work of the equipment,and can keep the function of the equipment stable and reliable in the longterm operation.The overall design has a very broad application prospect.Intelligent construction of high-voltage substation makes up for many deficiencies of traditional substation by adopting advanced digital technology and more perfect safety measures.This paper,through the design of intelligent control system of auxiliary equipment,actively promotes intelligent construction of substation and improves real-time monitoring ability,adaptive control ability,fault warning ability,data processing ability and other aspects of substation.So as to achieve more efficient,safer,more stable power system operation.
