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, the central control equipment 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 does not match, and the central control equipment 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 understand that ...

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 present invention relates to the technical field of automatic control of power systems, and in particular to a technology for automatic control of switch units in power systems. Background technique [0002] With the continuous development of social economy, all walks of life have become more and more dependent on electricity, and have higher and higher requirements for power supply reliability. At the same time, the scale of the power system continues to expand and the complexity of the system continues to increase. The infrastructure and operation and maintenance system pose huge challenges, especially in the face of the huge scale of the park, how to improve the automatic operation of the power system and reduce maintenance and management costs through a solid and reasonable automatic control system under the premise of ensuring safe and continuous power supply , Has become a problem faced by power system construction and operation and maintenance ma...
