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

Abstract
The invention discloses a distributed optical character alarm system and method facing a hydropower industry. The distributed optical character alarm system comprises an acquisition system, a distributed monitoring alarm system, an optical character alarm redundancy system located in a monitoring center and an optical character alarm information display unit. In the invention, pre-judgment of alarm information is completed locally at a terminal, and optical character alarm signals are preprocessed locally according to importance and an emergency degree of the signals, screening, optimization,analysis and prediction and the like are included so that simplification of a data volume is ensured, a burden of background data processing is reduced, and accurate and real-time display of various optical character alarm information of a hydropower station is realized. The burden of local data processing is further reduced through collection system classification, redundancy of a hardware structure of a whole system is decreased, and system cost is reduced. The system and the method are used to assist operation and maintenance personnel to process the alarm information timely, efficiently and stably, and have a 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,...
