Abstract

The invention discloses a method for the configuration optimization and the operation control of controlled phase shifters, and relates to a method for construction planning and the operation control thereof for alternating current main lines or alternating current distribution network, particularly to a method for the configuration optimization and the operation control of the controlled phase shifters for an ultrahigh voltage power transmission network based on improving the fracture surface conveying ability of the power network. The method comprises the following steps: obtaining node data of the fracture surface of the power network and planning configuration number of the controlled phase shifters, and building the node power balance equations of power systems of the controlled phase shifters; building an optimal tidal current mathematical model stated by solving; determining the optimal configuration state of the controlled phase shifters according to the configuration states of the controlled phase shifters when the transmission capacity of the comprehensive fracture surface is greatest; adjusting the operation mode and the phase shifting angle of each controlled phase shifter according to an operation control parameter list. Through configuration optimization and the operation control of the controlled phase shifters, the method enables the fracture surface conveying ability of the power network to be nearly improved to the theoretical thermal stability limit of the fracture surface.

Description

technical field [0001] The invention relates to the construction planning and operation control method of an AC main line or an AC power distribution network, in particular to a controllable phase shifter configuration optimization and operation control method for an ultra-high voltage transmission network based on improving the transmission capacity of a grid section. Background technique [0002] Since the power system is constrained by the thermal stability limit of the equipment, the voltage drop constraint of the transmission line, the N-1 static security constraint, the system small disturbance stability constraint, the voltage stability constraint, the transient stability constraint and the reliability backup constraint This makes it difficult to fully utilize the power transmission capacity of the system. The power system is a historical process that develops gradually with the development of society and economy. Therefore, it is impossible to consider the far future...
