Problems solved by technology

[0002]The three-stage factory power backup automatic switching logic with tie bus has flexible and diverse operation modes due to the existence of the tie bus. Due to the requirements of this operation mode, the backup power supply cannot be automatically switched on after the busbar loses power, which increases the risk of plant power loss.

Embodiment Construction

[0024] Attached below Figure 1-2 Further describe the technical solution of the present invention in detail, but the protection scope of the present invention is not limited to the following description.

[0025] The present invention optimizes the design for the different operation modes of the three-section utility power with connecting busbars, and designs 8 automatic switching modes for the two sections of load-bearing busbars (I busbar and II busbar), which can realize the incoming line switch with The normal operation mode of the busbar and the automatic switching function of the backup power supply for the busbar with load under the special operation mode of the tie switch with the busbar to ensure the reliability of the power supply.

[0026] See figure 1 . The Ⅰ and Ⅱ busbars are externally connected to the incoming line switches 1DL and 2DL in the station, and run with load; the Ⅲ busbar is used as a connecting busbar, without load, and only externally connected t...

Abstract

The invention discloses a three-section type station service spare power automatic switching method with an interconnection bus, and relates to the technical field of power systems. The method comprises a normal operation mode and a special operation mode, the normal operation mode is that an incoming switch operates with a load bus, and the special operation mode is that the interconnection switch operates with the load bus. A bus I and a bus II are externally connected with incoming line switches 1DL and 2DL in a station to operate with load, a bus III is used as an interconnection bus without load and is externally connected with a construction power supply and an emergency power supply switch 3DL, and eight automatic switching modes are designed for the bus I and the bus II with load respectively. The standby power supply automatic switching function of the on-load bus power loss under the normal operation mode of the incoming switch with the bus and the special operation mode of the interconnection switch with the bus can be realized, and the reliability of power supply is ensured.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a three-stage self-switching method for factory power equipment with connecting busbars. Background technique [0002] The three-stage factory power backup automatic switching logic with a connecting busbar has flexible and diverse operation modes due to the existence of the connecting busbar. The ordinary backup automatic switching logic cannot meet the requirements of various operating modes, resulting in the inability to automatically switch on the backup power supply after the busbar is powered off. , increasing the risk of plant power loss. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a three-stage factory-use automatic switch-on method with a tie bus. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A three-s...
