Remote local switch with remote authorization control function and mode control method

Abstract

The invention discloses a remote local switch with a remote authorization control function and a mode control method. The remote local switch comprises a shell, a touch display screen, a central processing module, a communication module and a switch execution module, and the switch execution module comprises a local mode relay and a remote mode relay. the mode control method of the remote local switch comprises a local control method and a remote control method. The local control method specifically comprises the following steps: setting an operation password in the central processing module;and when the user changes the local mode, inputting an operation password through the touch display screen for verification. The remote control method specifically comprises the following steps that after a user completes authentication in the remote authorization system, a remote local switch is set to be in a remote operation mode through the remote authorization system. The safety performance of the remote on-site switch can be improved.

Description

technical field [0001] The invention relates to the technical field of remote control in electric power systems, in particular to a remote local switch with a remote authorized control function and a mode control method. Background technique [0002] Currently, most of the remote local switches installed in substations are basically handle type mechanical multiplexer switches. Although such a structure is relatively simple, it greatly increases the potential safety hazard of remote control during use. The specific manifestations are as follows: 1. In the process of manual operation, if the position is not returned in time after the position is set, there will be a phenomenon that the telecontrol operation cannot be performed in the remote place of dispatching. 2. Misoperation occurs during human operation, because the toggle switch has not been certified before, and can be operated directly. Since most of the substations now adopt an unattended management mode, once someon...

Problems solved by technology

Although such a structure is relatively simple, it greatly increases the safety hazard of remote control during use.

The specific manifestations are as follows: 1. In the process of manual operation, if the position is not returned in time after being set, there will be a phenomenon that telecontrol operation cannot be performed in the dispatching remote place

2. Misoperation occurs during human operation, because the toggle switch has not been certified before, and can be operated directly

If remote operation is required at this time, it will not be possible

3. It is impossible to switch the state of the switch remotely, and it is impossible to achieve this purpose through the improvement of simple structure

In addition, the remote control authorization system has been added and modified in the current power grid system, but the original single mechanical remote local switch no longer has the ability to be connected to the system

Newly installed terminal equipment that matches the remote control authorization system will cost more money and increase failure points
