Distributed optical word alarm system and method for hydropower industry

Abstract

The invention discloses a distributed optical word alarm system and method for the hydropower industry, comprising: a collection system, a distributed monitoring alarm system, an optical word alarm redundancy system located in a monitoring center, and an optical word alarm information display unit. The present invention completes the pre-judgment of the alarm information locally at the terminal, and preprocesses the optical word alarm signal locally according to the importance and urgency of the signal, including screening, optimization, analysis and prediction, etc. to ensure the simplification of the data volume and reduce the background data. The burden of processing realizes the accurate and real-time display of various optical word alarm information of hydropower stations; the burden of local data processing is further reduced through the classification of the collection system, the redundancy of the entire system hardware structure is reduced, and the system cost is reduced. The invention assists operation and maintenance personnel to process alarm information in a timely, efficient and stable manner, and has great application value.

Description

technical field [0001] The invention relates to an electric power monitoring system, in particular to a distributed optical word alarm system and method for the hydropower industry. Background technique [0002] According to the development plan of the Lancang River hydropower station, a total of 14 cascade hydropower stations will be developed on the main stream of the Lancang River in Yunnan Province, from the upstream ancient hydropower station to the downstream Olive Dam hydropower station, with a total installed capacity of about 24.81 million kilowatts. At present, the centralized control center has been connected to Wulonglong, Lidi, Huangdeng, Dahuaqiao, Miaowei, Gongguoqiao, Xiaowan, Manwan, Nuozhadu, Jinghong, Longkaikou, Ruilijiang, Shilin Photovoltaic, Xucun and other 15 power plants have realized remote centralized control functions for power plants such as Miaowei, Gongguoqiao, Xiaowan, Manwan, Nuozhadu, and Jinghong, with a monitoring data volume of about 270,...

AI Technical Summary

Problems solved by technology

[0003] The hydropower monitoring system manages and controls the auxiliary operation monitoring tasks of 15 power stations. During the actual operation, many problems were found: a large amount of monitoring information, a large workload of personnel, remote signaling of the amount of information connected to the system, and complicated telemetry data points. The remote signaling information is collected into the monitoring center and the quantity is large

Under normal circumstances, there are as many as 100 pieces of information uploaded per minute on average, but the monitoring screen window can only display 20 pieces of information at a time, and the rest of the information is pushed to the historical screen, so the monitoring personnel cannot check all the monitoring information in time. It takes a long time to query historical data, and new information is still being uploaded continuously, which affects the correct judgment of the fault point of the monitoring system and monitoring personnel, and delays the time for handling accidents
