Embodiment Construction

[0021] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] The present invention proposes a full-parameter adjustment control method for a hydroelectric generating set, that is, on the control system of a hydroelectric generating set, the three parameters of the guide vane opening, blade opening, and water wheel speed are optimized by the hydroelectric generating set Adjust to achieve the highest efficiency or maximum output of the unit.

[0023] like figure 1 As shown, in principle, v is the absolute speed, w is the relative speed, u is the implicated speed, v=u+w, For the variable speed unit, due to the change of n in the inlet and outlet velocity triangle of the turbine, u is adjusted, and the relative relationship between w and v is improved, that is, the inflow and outflow conditions are changed, and the ...

Abstract

The invention discloses a method for adjusting and controlling all parameters of a water-turbine generator set, which comprises the following step: based on the most advanced guide vane and blade double-regulation water-turbine generator set (KAPLAN type) at present, carrying out optimal adjustment on three parameters of the water-turbine generator set, namely, guide vane opening, blade opening and water-turbine rotating speed through an intelligently-optimized intelligent algorithm model to realize highest efficiency or maximum output of the generator set and obtain an optimal operating point. According to the method, the optimal solution of a feasible solution domain formed by all the adjustable parameters of the water-turbine generator set can be obtained to realize the target of highest efficiency or maximum output on a whole operation domain of the water-turbine generator set; and compared with the efficiency of the most advanced double-regulation generator set at present, the efficiency is improved by 3-10 percent, therefore, the method is a new breakthrough for realizing efficient and economic operation of a hydropower station.

Description

technical field [0001] The invention relates to a full adjustment method of a hydroelectric generating set, that is, on the basis of the most advanced guide vane and paddle double-adjusting hydroelectric generating set (KAPLAN type), the speed adjustment function is added, and specifically relates to a hydroelectric generating set. A full-parameter regulation control method for a turbine-generator set. Background technique [0002] Today's energy situation is tense. The depletion of non-renewable resources such as petroleum and coal has made people increasingly dependent on renewable resources. This is the main reason why hydropower, wind power, and solar power can flourish. Among the many renewable energy sources, hydropower is the most economical. However, people's attention often only stays in excavating new water energy resources, but ignores the technical transformation of the original hydropower generating equipment to improve the power generation efficiency. With ...
