Equipment safety online evaluation method and system for thermal power plant

Abstract

The embodiment of the invention provides an equipment safety online evaluation method and system for a thermal power plant. The method comprises the steps that collecting boiler equipment operation parameters of the thermal power plant in real time; performing data cleaning on the collected boiler equipment operation parameters to obtain effective values of the boiler equipment operation parameters; and performing safety evaluation on the effective value of the boiler equipment operation parameter by utilizing the selected boiler equipment safety online evaluation algorithm and combining a preset weight factor of the boiler equipment. Compared with a traditional method that safety evaluation is carried out through manual inspection and technician data monitoring, the method provided by theinvention can improve the accuracy of safety evaluation and effectively reduce the monitoring workload of technicians. According to the method, safety evaluation can be conducted on the operation parameters of all the devices, safety evaluation can also be conducted on the whole boiler, the mode is flexible, different device evaluation results can be achieved according to the attention points ofusers, and actual operation can be guided.

Description

technical field [0001] The invention relates to the field of equipment safety assessment in the coal-fired electric power industry, in particular to an online equipment safety assessment method and system for thermal power plants. Background technique [0002] At present, coal blending in my country's coal-fired power plants has become an inevitable choice. In the state of coal blending and blending, because the boiler usually blends and burns low-quality coal, the total amount of coal will increase, the output of coal mills, fans and other auxiliary equipment will increase, and the wear of the flue will also increase. At the same time, the furnace The distribution of wall temperature and heat load distribution in the furnace will also be very different from the design coal type, and these will lead to safety problems of the boiler. The safety of power plant equipment is the basis of its production, and only under the premise of ensuring safety can economic and social benef...
