Embodiment Construction

[0012] A method for checking substation information points without power outage. After the station-side telecontrol forwarding table is made according to the approved information point table, the remote signaling information is checked one by one with the dispatching master station database through the station-side telecontrol forwarding table. The telemetry information is converted from the secondary value displayed by the secondary equipment at each interval to obtain the actual primary value, which is checked with the primary value displayed by the master station; the remote control and remote adjustment operations are sent by the master station to send a remote control back-to-school command, and communicate with the station end The secondary device checks by receiving the back-to-school information for comparison.

[0013] The remote signaling information is carried out in the form of one-by-one checking between the station-side telecontrol forwarding table and the dispatc...

Abstract

The invention discloses an uninterrupted checking method for information sites of a substation. A station-end telemechanical forwarding table is made according to an audited and approved information site table; remote signaling information and a dispatching master station database are checked term by term through the station-end telemechanical forwarding table; for the remote signaling information, an actual primary value is converted through secondary values displayed by secondary devices of various intervals and is checked with the primary value displayed by a master station; and remote control and remote regulating operations are checked by issuing a remote control reverse check command through the master station and comparing with reverse check information received by a station-end secondary device. By the uninterrupted checking method for the information sites of the substation, the information sites of the substation can be quickly and accurately checked in an uninterrupted state.

Description

technical field [0001] The invention relates to a substation information point check technology, in particular to a substation information point check method without power failure. Background technique [0002] Substation information point check is a key task before substation construction, renovation and commissioning. Its purpose is to ensure the accuracy and timeliness of uploading various information of substations. According to the requirements of the State Grid Corporation's "large-scale operation" system construction, all substations in the region are centrally monitored by the city-level dispatching center. All substations have abolished the original CDT analog channels and adopted 104 data private network channels, so all substations need to re-check information points. On the other hand, with the acceleration of power grid construction, the workload of information point verification is increasing exponentially. However, the original information point checks all ...
