Abstract

The invention belongs to the electrical network voltage idle work automatic control technology area, its characteristic lies in based on the electrical power system network parameter and various generatrixes pitch point voltage, current, the merit and the reactive power actual value formed the Jacobian matrix, find out the actual sum lose value; again construct the optimization objective function to obtain the minimum value of the system sum active lose; then formed the discrete logic event, solved the optimization objective function to get the voltage value, the voltage value of idle work compensation node and the transformation ratio value on load tap changing transformer as the control command output, in order to adjust the above node parameter. The invention guarantees the voltage quality and simultaneously enhances the movement efficiency.

Description

technical field [0001] The technical invention belongs to the automatic control method of voltage and reactive power in large-scale regional power grids, provincial power grids and regional power grids of power systems. Background technique [0002] The development of the power system has prompted people to make continuous efforts to improve the security and stability of the power system, especially the emergence of the power market has put forward higher requirements for the stability of the power system, and has brought new challenges to the safe and stable operation of the power system. features. Generally, power plants are far away from the load center, but due to factors such as economics and environmental protection, on the one hand, the development of some power networks cannot keep up with the needs of the rapid growth of power loads, making some transmission lines in a state of heavy load or overload operation; on the other hand On the one hand, the implementation ...
