An intelligent quantitative weighted hydroelectric unit automatic power generation control system and algorithm

Abstract

The invention relates to a technical field of power grid generation control, in particular to provide an intelligent quantization weighted hydroelectric generating set automatic generation control system and arithmetic which comprises four functional modules: an electrical system zone control deviation calculation module, an intelligent quantization weighted automatic generation control module, a hydroelectric generating set subnet unbalancedness optimal operation output allocation module and a parameter self-adjusting optimal computation module. The intelligent quantization weighted hydroelectric generating set automatic generation control system and arithmetic is capable of quickly compensating random wavy load and the disturbance which the power imposes on line frequency and power balance, improving mains supply power quality, increasing the ability that the power grid absorbs wind power to generate electricity and improving the stability of security of operation of the electrical system.

Description

technical field [0001] The invention relates to the field of power grid power generation control, in particular to an intelligent quantitative weighted hydroelectric unit automatic power generation control system and algorithm. Background technique [0002] With the support of the national new energy policy, many large-scale wind farms with random disturbances are integrated into the power grid. At the same time, a large number of fluctuating loads containing power electronic devices, such as electrified railways, are connected to the power grid, which brings great benefits to the smooth operation and safe dispatch of the power grid. A certain difficulty. The traditional automatic power generation control method overuses the integral link, which is slow in responding to fluctuating loads and power sources, and cannot adapt to the needs of modern power grids for rapid adjustment of system frequency and power fluctuations.

The traditional automatic power generation control method overuses the integral link, which is slow in responding to fluctuating loads and power sources, and cannot adapt to the needs of modern power grids for rapid adjustment of system frequency and power fluctuations

In the modern power grid, the thermal power units that bear the main load have poor regulation characteristics, and the wind power and nuclear power units basically do not have the ability to quickly adjust output
