Abstract

The invention discloses a method for modeling an automatic power generating control model in power system stimulation, which models an automatic power generating control system by considering the control mode and the control performance evaluation standards in the automatic power generating control and the algorithm characteristics of power system stimulation. Meanwhile the invention discloses a method for implementing an automatic power control model in power system stimulation. The model can stimulate the three modes of constant-frequency control, constant-exchange power control and tie-line power and frequency deviation control in automatic power generating control, and simultaneously achieves the three control performance evaluation standards of A1/A2, CPS1/CPS2 and T of automatic power generating control; regions adopt different control strategies according to different region control performance evaluation standards, so that the model can analyze the influence of automatic power generating control in the long-term dynamic stimulation in a power system, and the requirement of the simulation of of the whole process of electromechanical transient and electromechanical medium and long-term dynamic state of the power system are met.

Description

Technical field [0001] The invention involves the field of power systems, and specifically involves a modeling method for automatic power generation control models in a power system simulation. Background technique [0002] With the improvement of the development and control requirements of the connected power grid, power grids in various regions have actively used AGC to automatically control the power grid, optimizing the quality of the grid operation, and reducing the work pressure of the dispatcher. [0003] At present, the AGC system is mainly used for the scheduling operation control of the provincial and above power grids at the State Grid Corporation, and nearly 30 adjustment centers, including national adjustment, network adjustment and provincial adjustment, have already possessed the AGC system.The manufacturers of the AGC system are Beijing Kodon Company and Nanrui Technology Company. The principles of the two companies AGC products are the same and the function is si...
