Problems solved by technology

In the large operation mode, the monitors can complete the remote monitoring and control of the power equipment in the jurisdiction area in the dispatching room. At present, the system does not have anti-error measures for the remote control of the monitors, and can only rely on the monitors to follow the power operation method, but this The manual guarantee method is obviously low in reliability. If the monitor does not operate properly, it is likely to cause power failure and affect the quality of power supply.

Embodiment Construction

[0020] The anti-error control method is a system control method applied to the large operation mode of the power grid dispatching automation system to ensure the accuracy of remote control and improve the safety and reliability of the large operation mode.

[0021] To run this error prevention control method, it is necessary to import the substation name information and the corresponding device number in the substation in the system data in advance, import the operator password and supervisor password, and also need to set up a database background control system, which can modify these data, Update.

[0022] In this regard, the system’s error prevention control methods are as follows figure 1 As shown, the details are as follows:

[0023] The switch remote control lockout is normal, and the remote equipment cannot be controlled in this state;

[0024] When remote control is required, after manually unlocking the switch, enter the name of the substation where the remote-controlled dev...

Abstract

The invention discloses an error control method for a power grid dispatching automation system in a full-operation mode. The error control method includes turning off a remote-control switch into a normal state, inputting the name of transformer substations where remotely controlled equipment located and numbers of the remotely controlled equipment after manually turning on the remote-control switch, checking whether the input names of the transformer substations match with the numbers of the remotely controlled equipment or not, turning off the remote-control switch if the checking result is Wrong, keeping the remote-control switch on if the checking result is Correct, and then entering an operation interface of the remote-control switch. The error control method is reasonable and scientific, capable of reducing error greatly and improving quality of power supply service.

Description

Technical field [0001] The invention relates to a control method for preventing misoperation in a power grid dispatching automation system. Background technique [0002] The power grid dispatching automation system is an important tool for power grid dispatching and substation monitoring, and the large operation mode is a mode of implementing a large-scale unified dispatching management of the power grid in the power grid dispatching automation system, and it is a remote power control system. The supervisor of the large operation mode can complete the remote monitoring and control of the electric equipment in the jurisdiction in the dispatching room. At present, the system does not have anti-error measures for the remote control of the supervisor, and can only rely on the supervisor to follow the electric operation method. The manual guarantee method is obviously low in reliability. If the monitor does not operate properly, it is likely to cause power supply failure and affect th...
