Leakage diagnosis method and device and computer readable storage medium

Abstract

The invention discloses a leakage diagnosis method and device and a computer readable storage medium. The leakage diagnosis method comprises the steps that monitoring information for a high-pressure heater is acquired; judging whether the high-pressure heater is suspected to leak or not according to a pre-established fault logic tree and the obtained monitoring information; when the high-pressure heater is suspected to leak, performing a leakage test on the high-pressure heater through a preset test means; and when it is determined that the high-pressure heater leaks, alarm reminding is carried out in a preset mode. Due to the fact that the experience of the number of professional technicians can be converted into the fault logic tree, the fault logic tree can be applied to leakage diagnosis, automatic judgment of leakage faults of the high-pressure heater is achieved, and the leakage phenomenon can be found in time.

Description

technical field [0001] This article relates to fault diagnosis technology, especially to a leak diagnosis method, device and computer-readable storage medium. Background technique [0002] The high-pressure heater is one of the main thermal equipment of the thermal power generating unit. If the heater leaks seriously, causing the heater to be full of water, it will endanger the safe operation of the unit. The performance and operational reliability of the high-pressure heater directly affect the safety and economy of the unit's operation. For a long time, due to reasons such as design, manufacture, installation and operation, the leakage of the heater has occurred frequently, which not only affects the load of the unit, but also In addition, due to the drop of feed water temperature, the thermal efficiency of the entire unit is reduced, which affects the power generation energy efficiency level of the unit.

If the heater leaks seriously, causing the heater to be full of water, it will endanger the safe operation of the unit

The performance and operational reliability of high-pressure heaters directly affect the safety and economy of unit operation. For a long time, due to reasons such as design, manufacture, installation and operation, heater leakage has occurred frequently, which not only affects the load of the unit, Moreover, due to the drop of feed water temperature, the thermal efficiency of the whole unit is reduced, which affects the power generation energy efficiency level of the unit.

[0003] In the prior art, the leakage inspection of high-pressure heaters is mainly carried out manually, but the monitoring and inspection of large-scale high-pressure heaters is very labor-intensive, and it is easy to exceed the working capacity of the staff on duty, resulting in untimely leakage inspection, resulting in Serious consequences
