Embodiment Construction

[0048] The present invention will be further described below in conjunction with drawings and embodiments.

[0049] figure 1 For the system deployment diagram: figure 2 For the overall function diagram: the giant hydropower plant intelligent alarm threshold setting method provided in this embodiment includes the following steps:

[0050] Obtain dynamic data, specific parameters and status information of various systems in hydropower plants;

[0051] Obtain the alarm threshold value of each system of the hydropower plant. The alarm threshold value is obtained by using the iterative learning control method, as follows: the error information measured in the previous time or the previous several times is corrected and input, so that the alarm value gradually approaches Reasonable, multiple iterations are carried out according to the strategy, and it has the function of self-learning and artificial correction, so as to repeat it, and finally realize the intelligent setting of th...

Abstract

The invention discloses a giant hydraulic power plant intelligent alarm threshold setting method. The method comprises the following steps: firstly, acquiring dynamic data, specific parameters and state information of each system of the hydraulic power plant; then acquiring an alarm threshold value of each system of the hydraulic power plant, monitoring data of each system according to the alarm threshold value, and if the data exceed the alarm threshold value, sending an alarm signal; and if the alarm threshold value is not exceeded, returning to recycle. According to the method provided by the invention, intelligent alarm threshold setting is carried out through big data calculation and trend analysis, so that an alarm system is more stable and reasonable; the linkage of the dynamic dataplatform and the computer monitoring system is realized through the setting of the intelligent alarm threshold value, the power plant resources are effectively integrated, the informatization and intelligence levels of the power plant are improved, the daily workload of operation and maintenance personnel is greatly reduced, and a guarantee is provided for the early warning of equipment and the long-period safe and stable operation of a unit.
