Based On PLC Shaft Tubular Hydro Turbine Control System Design

Water resource is a clean energy and renewable energy,so reasonably exploiting and utilizing of hydropower resource are the important supporting of China's economic and social sustainable development.The central committee of the communist party of China puts forward that we should accelerate the development of hydropower resources,vigorously develop hydropower under the premise of protect the interests of farmers in2011.According to China's energy development plan,by 2020 the national hydropower total installed capacity will reach to 420 million kilowatts,small hydropower will 75 million kilowatts.Hydropower station sithe research object.According to the actual situation of power station,we select the shaft tubular turbine units and the digital valve programmable intelligent governor.Main control layer to control,protect and measure mainly mechanical and electrical equipment and auxiliary equipment in power station,and comprehensively monitoring its running state.Achieve the communication between the dispatching department and monitoring system.Field control unit layer of main units of data and processing,with functions of monitoring,control and operation.The application of HG3000 configuration software in hydropower station monitoring system,the operation of the software is convenient and flexible station and has powerful function,friendly man-machine interface.Operators click index button in the monitoring system,can enter the monitoring index system,and operating process will show on the flow chart of monitor screen.Operation is simple,and the picture is clear.Finally,we evaluate the disadvantages of design in this power station,and the development of power plant is discussed.Power plant has been running at present,the actual running results show that can meet the requirements of practical application,and achieve the expected goal.The system not only play a positive role to relieve the tense situation of local power supply,and meet the requirements of ecological hydropower development.Power station upstream has a few kilometers of landscape,can improve the microclimate in the city,and optimize the humanistic harmonious environment.
