Research on WebGIS for Small Hydropower Groups Based on ASP.NET

This paper proposes a WebGIS based on ASP.NET for small hydropower station group, aiming to solve the problems of traditional WebGIS operation data of small hydropower station group cannot be transmitted in real time, the system stability is insufficient, and it does not support the visualization operation of vector graphics, etc. The MVC design pattern is used to make the system structure more clear through its model-viewcontroller separation strategy. The use of MVC design pattern through its model-view-controller separation strategy makes the structure of the system clearer and improves the maintainability and scalability of the system. The browser uses JavaScript to render graphics and draw dynamic graphics, which enriches the user experience. Tile map technology is applied to the system to localize the map data required for GIS of small hydropower station groups. Real-time power, operating head, installed capacity and other data of small hydropower stations are realized to be transmitted between the cloud server and the client in real time by WebSocket technology. Web Storage technology is utilized to store the data to the local client, reducing server requests. According to the actual operation, the system can display the geographic information and operation status of the hydropower station in real time and accurately, providing a comprehensive management platform for the dispatchers of small hydropower stations.
