Research On Reform Scheme Of Integrated Automation System For 110 KV Substation

The substation integrated automation system integrates various emerging technologies,realizes the optimization of the functions of the secondary equipment in the substation,so as to realize the efficient monitoring of the operation of the substation,and provides the integrated solution of monitoring,measurement,control and coordination.Up to now,although a series of phased achievements have been made in the development of substation integrated automation,influenced by the existing professional division of labor,technical barriers,thinking set,operation and maintenance habits,and even the distribution of interests,the promotion and deepening of intelligent substation technology still encounter various internal and external "bottlenecks",and there is still a large space for optimization and upgrading.Therefore,it is necessary to study more efficient and reliable intelligent substation technology to achieve more reliable substation integrated automation.In this paper,the comprehensive automation system of 110 kV Park substation is reformed.Based on its operation status,the transformation scheme is proposed and detailed configuration design is carried out.The main work is as follows:1)carry out analysis and Research on the operation status of 110 kV Park substation,from the aspects of grid status,load forecasting and power balance analysis,and analyze the operation status of integrated automation system of 110 kV Park substation,so as to analyze the necessity of project construction.From the three dimensions of Huizhou City,Huicheng District and near district power grid,grasp the current situation and future development of the power system in the region where it is located,analyze the requirements for the operation of the substation in the future,further study the operation of the station integrated automation system,further elaborate the necessity of the project transformation,and provide the background for the subsequent integrated automation system transformation.2)based on the analysis of the existing problems in the comprehensive automation of 110 kV Park Station,the root causes of the problems are dug out,the corresponding improvement ideas are put forward,and then the relevant transformation scheme is designed.Starting from the operation status of the integrated automation system,this paper analyzes the existing problems and puts forward the transformation ideas;at the same time,it also analyzes the communication system,excavates the problems and puts forward the transformation scheme.3)based on the transformation scheme of the station integrated automation system mentioned above,the networking mode of the secondary system is designed,and the optimal selection of the secondary system configuration scheme is carried out based on the AHP evaluation.From the perspective of the automation system architecture,the optimized configuration method is proposed in terms of protection,lightning protection,AC / DC power supply,etc.,which provides details for the upgrading and transformation of the 110 kV Park substation integrated automation system Detailed configuration scheme.Through the comprehensive automation transformation,110 kV Park substation can realize unattended,improve the safe and stable operation level of the system,improve the quality of power supply,promote the economic development of the region,and have greater economic and social benefits.
