Embodiment Construction
[0044] The method for judging remote information in the power dispatching system provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0045] The method for judging remote information in the power dispatching system provided by the present invention can make all five channels between the main station end and the station end transmit data, and the main station end can comprehensively judge the remote information of the station end according to the real-time data of the five channels. Telemetry information, including remote signaling signal discrimination methods and telemetry signal discrimination methods; where:
[0046] Such as figure 1 As shown, the described remote signaling signal discrimination method includes the following steps performed in order:
[0047] Step 1. The S1.1 stage of establishing a remote signaling point: establish a remote signaling point at the station, whose remote...

A remote transmission information judging method in an electric power dispatching system comprises a remote signaling signal judging method and a telemetering signal judging method. The remote signaling signal judging method comprises steps as follows: establishing remote signaling points, acquiring the remote signaling value of each channel, acquiring the state value of each channel, determining the state calculation value of each channel, judging whether the current channel is normal or not, determining remote signaling calculation values, prompting channel faults, judging whether the remote signaling point output value is 1 or not, determining that the remote signaling point output value is 1, determining whether the remote signaling point output value is 0 or not, prompting that the current remote signaling value is incredible, and the like. According to the remote transmission information judging method in the electric power dispatching system, spare channels are fully utilized, five channels between a master station end and station ends are used, meanwhile, a set of transmission remote signaling and telemetering information is acquired, all channel data participate in information state calculation, so that the acquired information is more reliable, and the transmission fault tolerance capacity and the information reliability are enhanced.
Description
technical field [0001] The invention belongs to the technical field of power network information processing, in particular to a method for judging remote information in a power dispatching system. Background technique [0002] At present, the remote signaling and telemetry information required by the power dispatching center to understand the real-time status of the grid operation is provided by the remote machine at the substation end. In order to ensure the reliable operation of the system, the front-end machine at the general dispatching end (abbreviation: master station end) and the remote machine at the substation end (abbreviation: station end) adopt redundant configurations. There are two types of communication channels: network channels and private line channels. The current configuration method on the network channel is that any server at the master station can communicate with any remote machine at the station, that is, there are four network channels between the ...
