Problems solved by technology

[0003] The control system of the existing pumped storage unit is relatively simple, and there is no comprehensive consideration of all aspects that restrict the safe and stable operation of the pumped storage unit, resulting in a large discrepancy between the dispatch order and the actual operation. When the power generation command is issued, the unit can no longer generate power, which makes the command invalid and delays the opportunity to adjust the balance of the power grid

Embodiment Construction

[0013] Such as figure 1 As shown, it is a schematic diagram of a stable operation control system of a pumped storage unit. The system includes a dispatching side device and a pumped storage unit side device.

[0014] The dispatching side device includes a grid-side power detection device, a load-side power detection device, a comparison device, a control device, a grid-side communication device, a grid-side power detection device, and a load-side power detection device respectively connected to the two input terminals of the comparison device, and the comparison device The output end of the control device is connected to the control device, and the control device is connected to the network side communication device;

[0015] The grid-side power detection device detects the output of all power sources in the grid in real time, and the load-side power detection device detects all load demands in real time; the comparison device compares the power output and load demand, and whe...

Abstract

The invention discloses a stable running control system for a pump storage unit. The stable running control system for the pump storage unit comprises a dispatching side device and a pump storage unitside device. Due to the fact that the stable running control system for the pump storage unit is provided with the dispatching side device and the pump storage unit side device, interaction between the pump storage unit and dispatching is achieved, dispatching instructions can be received, meanwhile, emergency self control can also be achieved, then, self stability can be achieved in real time, and the situation that the adjustment opportunity is delayed is avoided.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution, in particular to a control system capable of realizing stable operation of a pumped storage unit. Background technique [0002] The pumped storage unit is different from the ordinary generator set. It can not only output power as a power source, but also store electricity as a load. The stable operation of the pumped storage unit depends on the coordinated action of the generator and the turbine. Therefore, compared with ordinary generating units, the operating conditions of pumped storage units are more complicated, and it is necessary to consider the output of pumped storage units, that is, the operation of the generator, and the hydraulic control, that is, the operation of the turbine. The condition of the reservoir also needs to be considered. [0003] The control system of the existing pumped storage unit is relatively simple, and there is no comprehensive consideratio...
