Abstract

The invention provides a whole plant water turbine speed regulation systems health state evaluation and optimization method. The whole plant water turbine speed regulation systems intelligent analysisplatform obtains characteristic parameters of all parts of the whole plant water turbine speed regulation systems through an industrial ethernet, the characteristic parameters of same components of different water turbine speed regulation systems in the whole plant are compared and calculated, a health state indexes of all the components of each set of water turbine speed regulation system are corrected, so that the health state of each set of water turbine speed regulation system can be evaluated more accurately and timely. The whole plant water turbine speed regulation systems intelligent analysis platform obtains information of water heads, active power, guide vane opening degrees and a vibration swing degree of whole plant water turbine generator sets through the industrial ethernet,a comprehensive characteristic curve of the water head, the active power, the guide vane opening degree and a electric operation limit of each water turbine generator set are founded through long-timeoperation data accumulation and analysis, and an ultra-limiting region of the vibration swing degree is identified, so as to optimize a power regulation and primary frequency modulation of the waterturbine speed regulation systems, thus the overload of the sets is avoided, meanwhile, the ultra-limiting region of the vibration swing degree is avoided.

Description

technical field

[0001] The invention relates to a method for evaluating and optimizing the health state of the speed regulating system of hydraulic turbines in the whole plant, which is used for evaluating the state of health and optimizing control of the speed regulating systems of various types of hydraulic turbines in intelligent hydropower stations, and meets the safe operation requirements of smart grids. technical background

[0002] The health and normal operation of the turbines in hydropower stations will directly affect whether there are potential safety hazards. There are many reasons for accidents and exposed problems. The most important reason is that the units are operating in the vibration area due to frequency modulation and peak regulation. Seriously exceeded. To this end, we must strengthen the monitoring of the condition of the unit and improve the stability of the unit operation. As the core control equipment of the turbine, the turbine speed control syst...
