System for distributing loads among plants of cascade hydropower stations in real time and implementation method of system

Abstract

The invention discloses a system for distributing loads among plants of cascade hydropower stations in real time and an implementation method of the system and mainly solves the problem that under the situation that a total power generation load instruction fluctuates frequently, the water level of a counter regulation power station reservoir cannot be controlled effectively to realize real-time coordinated operation of a cascade hydropower station group in the prior art. The system comprises a strategy library, a database server, a monitoring module, a strategy and model calculating module, a data transmission module, a fault alarm processing module and a prediction calculating module, wherein the prediction calculating module, the fault alarm processing module, the strategy and model calculating module and the data transmission module are respectively connected with the monitoring module. The strategy library is connected with the strategy and model calculating module. The database server is connected with the data transmission module. The system has the advantages that later effects of real-time distribution results of the loads among plants are considered, effectively scheduling of the cascade hydropower station group is achieved, and high practical and popularization values are achieved.

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a real-time load distribution system between cascade hydropower stations and its implementation method, which mainly solves the large difference in reservoir regulation performance between the regulation power station and the counter-regulation power station, the large proportion of the total installed capacity in its direct regulation grid, and the participation in grid regulation at the same time. Under the special combination of peak frequency modulation tasks, the real-time load distribution between cascade hydropower stations cannot effectively control the water level of the anti-regulation power station reservoir and realize the real-time coordinated operation of the cascade hydropower station group under the condition of frequent fluctuations in the total power generation load command.
