Therefore, in view of the above-mentioned problems, the present invention provides a kind of pump-storage generator dispatching method, by considering actually
The real time water level situation of reservoir, lower storage reservoir, can not only meet the equilibrium of supply and demand of electric system, but also can ensure upper and lower
The water level of reservoir is constantly in rational level, so as to ensure the safety of power plant, and also protects the natural, ecological of surrounding at the same time
Environment.
In order to achieve the above object, the present invention proposes a kind of pump-storage generator dispatching method, and this method includes：
1. sensed water level；
2. machine unit scheduling is realized according to water level.
The present invention is big between the numerical value of reservoir level up and down of collection and the high and low water level different stalls value of setting by comparing
It is small, different scheduling strategies is set for different comparative results, realizes and meets electric system peak-frequency regulation demand and power plant
Balance between safe and stable operation, surrounding natural environment are gentle so that operation plan more closing to reality, it is easy to carry out.
