Description
Technical Field
The invention belongs to the technical field of analysis of remote signaling actions of automation terminals, and relates to an analysis method of remote signaling action conditions of an automation terminal during power failure.
Background
For the practicability of the distribution network system, besides the acquisition type number can be received in a timing and triggering mode under a normal state, more important is that the switch tripping signal can be correctly and rapidly received when a fault occurs. Therefore, when the distribution network primary equipment has power failure, whether the automatic switch operates correctly or not needs to be checked, and an alarm needs to be sent. When a fault occurs, the distribution network terminal generally sends a switch trip signal to the main station and sends an SOE signal to the main station, and finally, the SCADA system processing logic is triggered to display the switch opening state in a graphical mode. Whether the primary equipment really acts or not, whether the telemetering displacement signal is correctly uploaded to the master station or not, whether the SOE signal is correctly uploaded or not and the SOE time is earlier than the telemetering displacement time are the key points of the problem. The current criterion for the fault is not clear enough, so that the information uploaded after the switch state changes is not known to be accurate or not.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the method for analyzing the remote signaling action condition of the automatic terminal during power failure is provided, and the problems in the prior art are solved.
The technical scheme adopted by the invention is as follows: a method for analyzing remote signaling action condition of an automatic terminal during power failure comprises the following steps:
1) the distribution network terminal is connected with the primary equipment (switch) by adopting an aviation plug, and the distribution network terminal can quickly receive corresponding signals after the primary equipment acts;
2) after receiving a switch opening and closing signal under a normal condition, the distribution network terminal transmits a switch displacement signal and an SOE signal to a distribution network main station through a protocol;
3) for data received by a distribution network main station, a device time mark is marked on an SOE signal, switch deflection is a message time mark received by the main station, and the SOE device time mark is earlier than that of the deflection signal because a terminal has transmission delay to the main station;
4) and screening each remote signaling point according to the criterion, making a record, and forming a statistical report summary according to the day.
The criteria are as follows:
1) the switch finally reflects that the position is indeed changed in the SCADA system and has a corresponding SOE signal, and the switch is considered to be successful, otherwise, the switch fails;
2) the SOE signal is earlier than the shift signal, and is considered to be successful, otherwise, the SOE signal fails;
3) empirically, the SOE signal is deemed authentic within 10 seconds of the deflection signal, and is recorded as successful, otherwise, it fails.
The invention has the beneficial effects that: compared with the prior art, the method and the device perform time-sharing statistics on success and failure conditions of the remote signaling action, present the real condition of the remote signaling action in a report form, provide powerful data support for team personnel, analyze the remote signaling action condition of the distribution network automation terminal, perform statistics on report output and analysis conditions, and enable the error rate of a statistical result to be lower than 0.001%.
