As the key equipment to regulate the flow and ensure the stable operation of the unit, the control technology of tailgate of hydropower station directly affects the whole performance and economic benefit of hydropower station. With the rapid development of automation technology, the application of advanced control technology to the management and operation of tailgate has become an important direction to improve the modernization level of hydropower station. Firstly, this paper analyzes the problems and shortcomings of traditional control methods of tailgate in hydropower station, such as complicated operation, slow response, high failure rate, and difficulty in adapting to complex working conditions. Then, the application principle and realization of automatic control technology in tailgate are deeply studied, including sensor technology, PLC (Programmable logic controller) technology, remote monitoring and communication technology, intelligent algorithm and so on. The application of these technologies makes the control of tailgate more accurate, efficient and flexible, and can realize the real-time regulation of water flow, early warning and automatic processing of faults, as well as remote monitoring and centralized management. On the basis of technical research, this paper also expounds the design and implementation of the automatic control system of tailgate in hydropower station with a concrete case. In the process of system design, the actual needs, environmental conditions, safety norms and other factors are fully considered to ensure that the system can meet the current operation requirements, and has good scalability and maintainability. In the process of implementation, attention is paid to the integration and debugging of the system, personnel training and technical support to ensure the smooth transition and smooth operation of the system. The research results of this paper not only provide beneficial reference and reference for the development of automatic control technology of tailgate of hydropower station, but also provide strong support for improving the overall operation efficiency and safety of hydropower station, reducing operating costs and realizing intelligent management. In the future, with the continuous innovation of automation technology and the continuous expansion of application fields, the automatic control technology of tailgate of hydropower station is expected to make more significant progress and breakthroughs.
