Problems solved by technology

[0013] (3) Aiming at the transition between states that may occur in the system, various logical relationships need to be preset, and those skilled in the art generally only preset part of the main process, and it is difficult to satisfy all operating states
Even if the logical judgment process of all states is preset in an exhaustive manner, the overall process will become unimaginably complicated and the reliability of the system will be reduced
[0014] (4) The basis for logical judgment is particularly important. If the setting is too strict, the system logic will be complicated and the reliability will be reduced; if the setting is too loose, it will make it difficult to grasp the parallel risk degree of the system logic.
[0015] (5) When it is necessary to adjust one of the logical judgment processes and corresponding operations, it is difficult to evaluate the impact of such adjustments on other operating steps

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] The present invention can be implemented by any device with central control capability, such as a central control device specifically. Specifically, the central control device determines the corresponding target connection state of the power system according to the current operating state of each input power source in the power system; then, if the current closed state of each switch unit in the power system corresponds to the target connection state The target closed state of each switch unit is not consistent, and the central control device adjusts the corresponding switch unit in the power system according to the target closed state.

[0041] For the sake of simple description, the present invention only uses the central control device to adjust the closed state of the switch unit in the power system as an example. Those skilled in the art should u...

Abstract

The invention aims to provide a method and a device for automatically controlling switch unit in an electrical power system. The method comprises the following steps: confirming the target connected state corresponding to the electrical power system according to the current running status of each input power supply of the electrical power system, if the current close state of each switch unit in the electrical power system disagrees with the target close state of the switch unit corresponding to the target connected state, adjusting the corresponding switch unit in the electrical power system according to the target close state.

Description

technical field [0001] The invention relates to the technical field of automatic control of electric power systems, in particular to a technology for automatic control of switching units in electric power systems. Background technique [0002] With the continuous development of social economy, all walks of life are more and more dependent on electricity, and the requirements for power supply reliability are getting higher and higher. At the same time, the scale of power systems is expanding and the complexity of systems is increasing. The infrastructure and operation and maintenance system pose huge challenges, especially in the face of a huge park scale, how to improve the automation of the power system and reduce maintenance and management costs on the premise of ensuring safe and continuous power supply through a solid and reasonable automation control system , has become a problem faced by power system construction and operation and maintenance managers. [0003] At pre...
