Problems solved by technology
[0004]1. The existing alarm system does not distinguish between levels, and all alarms are displayed on one alarm interface;
[0005]2. The existing alarm system does not automatically judge the operating status of the generating set, but only uses the alarm displacement mark to alarm (that is, alarm or not);
[0006]3. All alarms are in the form of voice alarms, making it difficult to distinguish important alarms;
[0007]4. There is no color distinction for alarm signals

Embodiment Construction
[0035] Such as figure 1 with figure 2 As shown, an intelligent alarm system for the operation interval of a hydropower generating set, the system is divided into a load classification monitoring system and an intelligent alarm system, the load classification monitoring system includes a load monitoring unit 1, and the load monitoring unit 1 collects the real-time load of the generating set and The load value is transmitted to the load verification unit 2, and the load verification unit 2 determines the specific interval of the real-time load of the generator set and judges whether the generator set belongs to the normal working position. When the generator set belongs to the abnormal working position, the load verification unit 2 sends an alarm signal Pass it to the load alarm unit 3 and issue an alarm, and the on-site staff finally reset the alarm system through the alarm reset unit 4;
[0036] The intelligent alarm system includes a state analysis module 5. After receiving...

A hydropower station generator set operation interval intelligent alarm system is divided into a load grading monitoring system and an intelligent alarm system, a load monitoring unit transmits a load value to a load verification unit, and when a generator set belongs to an abnormal working position, the load verification unit transmits an alarm signal to a load alarm unit and gives an alarm; a worker resets the alarm system through the alarm reset unit, the state analysis module analyzes the operation state of the generator set and then transmits an analysis result to an alarm grading module, the alarm grading module carries out signal grading according to the degree of an accident, and after grading is completed, an alarm signal is transmitted to the load alarm unit. The load alarm unit gives a corresponding alarm according to the signal level; a brand-new generator set operation interval distribution detection mode and a grading intelligent alarm system are adopted, the operation state of the generator set can be judged more reasonably through the system, and the alarm mode is simpler and clearer.
Description
technical field [0001] The invention belongs to the technical field of intelligent monitoring equipment, and in particular relates to an intelligent alarm system for the operation interval of a generating set of a hydropower station. Background technique [0002] In the current hydropower station monitoring system, the load range of the generator set is usually set to three sections. When the load of the generator set rises from zero to the maximum value, the load values of the first and last two sections are the recommended load value for operation, and the middle end is prohibited. Operating load value, the operation of the generator set within the prohibited operating load range will make the working condition of the generator worse, which will have a greater impact on the generator, but according to the current segmentation method, if the generator is within the prohibited operating load value Running at the edge of the operating load value, the operating condition o...
