Embodiment Construction
[0025] The technical content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] The safe remote control method provided by the present invention considers that the key link of remote control is the downlink remote control point table (hereinafter referred to as "remote control point table"), which is a relatively abstract data point number associated with the actual remote control object. In order to avoid data point number association failure, the present invention mainly protects the remote control point table. By adding the solidification point table, the remote command is processed before the man-machine interface sends information to the SCADA system, and the attribute information in the remote control point table related to the remote control object is compared with the property information in the solidification point table. Only when the information in the two tables is consistent, ...

The invention discloses a safe remote control method, and particularly relates to a safe remote control method for a power dispatching system. the method comprises the following steps: in the case of a remote control transmission test, a solidifying point table is generated according to downlink remote control points; a control point is selected for building a remote control instruction, and attribute information of a remote control object in the downlink remote control point table is acquired according to the remote control instruction; the solidifying point table is loaded, and attribute information of the remote control object in the solidifying point table and in the downlink remote control point table is compared whether to be consistent; if yes, remote control is executed; and if not, remote control is stopped. Through comparing the downlink remote control point table and the solidifying version, remote control safety and data uniqueness can be ensured, and hidden safety dangers caused when the downlink remote control point table is modified or deleted can be avoided.
Description
technical field [0001] The invention relates to a safe remote control method for a power dispatching system, and belongs to the technical field of power system dispatching. Background technique [0002] When the SCADA (Data Acquisition and Supervisory Control) system performs remote control of the power system, the monitoring personnel implement remote monitoring and control of substation equipment such as circuit breakers and transformer gears through the dispatching automation master station system (referred to as "master station system") . When the current SCADA system performs remote control, the operator selects a point on the man-machine interface to obtain relevant information such as the keyword of the remote control object, the control direction (open, close) or the gear value of the control object, and send it to SCADA The server is forwarded by the SCADA server to the front-end server for processing. However, the prior art lacks a necessary verification function...
