Embodiment Construction

[0013] The principle and specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Design a set of remote control authority restriction mechanism in the power dispatch automation real-time system, as far as possible, every automation personnel can set strict remote control authority restriction conditions for each remote control point on each operation node. In this way, when the automation personnel perform remote control operation on a host computer and select the switch (knife switch) that needs to be remotely controlled, the system uses this parameter and the pre-configured remote control authority constraints to check whether the constraints are met. Request to the system to perform a telecontrol operation.

[0015] In the power dispatch automation real-time system, 32 responsibility areas are preset for all equipment, and each remote control point in the system belongs to o...

Abstract

The invention discloses an anti-misoperation method for the automation personnel in the electric power system. The anti-misoperation method comprises the following steps: (1) firstly, logging in the nodes allowing the remote-control operations as a user having the remote-control permission, and selecting the remote-control objects; (2) reading a station remote-control information list and a remote-control prescription and permission list; and (3) firstly, judging whether the remote-control permission is allocated to the corresponding remote control object, if not, according to the test results, logging off the remote-control process, and if so, according to the test results, further verifying whether the permission is ineffective, if so, logging off the remote-control process, and if not, entering into the normal remote-control process. By taking the factors, such as operators, responsibility areas, nodes at which operations are performed, permission time limit and the like, into comprehensive consideration, the invention can not only achieve the flexible and simple permission allocation, but also guarantee the integrity of the permission constraints.

Description

technical field [0001] The invention relates to a method for preventing errors of electric power system automation personnel. Background technique [0002] The power department has always attached great importance to the safe operation of the power system, and has listed the prevention of electrical misoperation accidents as a major technical problem that needs to be solved urgently in power production. Operate the regulations of the guardianship system. The remote control operation in the power system is mainly completed by two types of personnel, one is the operation duty personnel, and the other is the automation personnel. But at present, the anti-mistake measures in the power system are mainly aimed at the operation personnel on duty, while the anti-mistake measures for automation personnel have been in a blank state. [0003] Therefore, from the technical point of view, safety factor, practicability and other aspects, it is the key point of the present invention to e...
