Embodiment
[0036] like Figure 1~2 In the shown embodiment, a voice-assisted alarm system and method for a mill group in a thermal power unit: the operation and adjustment of each mill group in the pulverizing system of the unit are frequent and abnormal in the daily production process, which is an important monitoring object. The relevant alarm settings in the DCS system are not sufficient, resulting in a large amount of work for the operator to monitor the disk, and the efficiency and quality are poor.
[0037] Through voice-assisted alarms, operators can set routine alarm items based on unit-related operating regulations, experience or historical data values. The special alarm function is used to extract the historical data of the relevant parameters, the machine learning method is used to build the model, and the reasonable judgment conditions are set to achieve a certain degree of early warning function.
[0038] The alarm system includes an information acquisition unit, a databas...

The invention discloses a thermal power generating unit voice auxiliary alarm method and system, and the method comprises the steps: obtaining the monitoring data of each detection element of a thermal power generating unit, and building a monitoring data sample library; setting alarm parameters of the monitoring elements, establishing an alarm database, and generating alarm information when the monitoring data of the monitoring elements meet alarm conditions; the alarm information is divided into a special alarm information list and a conventional alarm information list to be displayed; and broadcasting the alarm information content according to the list display sequence. The special alarm information list is used for displaying fault early warning information of the thermal power generating unit; the conventional alarm information list is used for displaying the equipment parameter alarm information of each equipment of the thermal power generating unit. Alarm information is divided into two types of alarm information lists to be displayed, and a fault early warning model is established to realize a certain degree of fault early warning function. Alarm information is sequentially broadcasted in a voice mode, and daily monitoring work of centralized control operation personnel of the thermal power generating unit is more scientifically and effectively assisted.
Description
technical field [0001] The invention relates to the field of electric power systems, in particular to a voice-assisted alarm method and an alarm system for thermal power units. Background technique [0002] The alarm system of large thermal power units is an important part of thermal automation control, and it is also a highly dependent system in the centralized monitoring process of operators. [0003] At present, most alarm systems are configured in two forms: list alarm and soft light plate alarm. Among them, the list alarm is displayed in the form of text by the window software provided by the DCS system software, and the information is comprehensive and the number is large; the soft light plate alarm is based on the power plant's own experience to adopt a certain alarm signal collection principle, imitating the early on-site photonic cards. Style, use DCS software to carry out configuration design, concentrate the important information in the list alarm into one pictur...
