Abstract

The invention discloses a thermal power generating unit AGC control method based on wind power load change speed and a thermal power generating unit AGC control system based on wind power load changespeed. The system comprises a real-time load measurement device, a deviation calculation module ADD, an absolute value calculation module, an input switching module T, a proportional coefficient adjusting module F1(x), an integral time adjusting module F2(x), a feedforward coefficient adjusting module F3(x), an AGC instruction input module, a feedforward instruction module MUL and an AGC PID controller. The technical characteristics of the wind power generating and thermal power generating AGC mode operation unit are comprehensively considered, the adjuster control parameters of the thermal power generating unit AGC control system in the power grid are dynamically changed according to the wind power generating load change speed in the regional power grid and the adjusting capacity of the thermal power generating unit AGC is enabled to be closely related to the change speed of the wind power generating load so that the quick adjusting capacity of the power grid can be enhanced on the basis of the stability of the control system and the technical support can be provided for stable operation of the power grid.

Description

technical field [0001] The invention relates to the technical field of thermal power unit control, in particular to an AGC control method and system for thermal power unit based on wind power load change speed. Background technique [0002] At present, with the maturity of wind power technology and equipment, wind power has developed rapidly. The installed capacity of wind power and the proportion of power generation load in the power grid are increasing. In some regional power grids, the development speed of wind power has exceeded that of conventional thermal power. The development speed of power generation and the composition and structure of the power grid have undergone major changes. The rapid growth of new energy power generation scale has also brought about consumption problems. Completely different from traditional energy sources, new energy has the characteristics of large randomness, fast change speed, and poor adjustment ability. Large-scale new energy grid-conne...
