Description
Technical Field
The invention belongs to the field of power generation, and particularly relates to a whole plant valve operation management method for a power plant.
Background
In modern society, various power plants are the foundation of the modern energy industry. In various pipeline systems of power plants, the valve is used as the throat of various pipelines, which plays a very important role. The performance and quality of the valve and the problem of misoperation of the valve by operators cause leakage, production halt and major accidents, and bring immeasurable loss to the normal operation, personal safety, property and the like of industrial production. According to the statistics, significant production accidents are caused in the world every year, wherein 1/3 is caused by valve accidents, and particularly in the power industry, economic losses caused by abnormal operation of valves are considerable, so that the method has important significance for operation management of valves of power plants.
At the present stage, the domestic large power station does not pay enough attention to the operation management of the valves of the whole plant, and a special valve operation management system is not provided, so that the operation management of the valves basically adopts the following two modes:
1. for the automated valve: various electric doors and adjusting doors of the DCS are accessed, the valves are remotely operated and monitored by operators, and when problems occur in remote operation, corresponding fault treatment stages are carried out;
2. for the manual valve: the valves are mostly stop valves, operators hold corresponding operation tickets to perform local manual operation, the name and operation instructions of the valves are marked on the operation tickets, the operators check the relevant names after arriving at the specified valves to perform operation, and when faults are found, the corresponding fault processing stage is started;
for such a management mode, there are several disadvantages:
1. hysteresis in finding valve failure: because a special valve operation management system does not exist, some valves which are not operated frequently have problems, and the faults are discovered after a long period of time, so that great economic loss is caused or great potential safety hazards are generated when the faults are discovered;
2. great misoperation hidden danger: for on-site manual doors, after the manual doors are operated for a period of time, name boards or marks arranged conventionally are lost frequently, and operators often have misoperation under the condition that the operators are not familiar with the system or execute a two-ticket system, and the fact also proves that accidents caused by various misoperation of the operators of domestic power plants on the valves at the present stage still account for a large proportion of production accidents in the power industry.
3. The state of the valve cannot be accurately grasped: because a special valve operation management system does not exist, the state of each valve cannot be accurately mastered, the operation maintenance of the valves is stopped in a negative feedback mode of 'defect finding-defect elimination', for some important valves, once defects occur, serious consequences are easy to generate, and the existing valve operation management mode cannot achieve early warning.
4. The maintenance and management of the valves are difficult, and similarly, due to the fact that no special valve operation management system exists, in the daily operation process of a power plant, some valves work in abnormal states for a long time or perform irregular operation for a long time, the service life of the valves is greatly shortened, and the operation and maintenance cost of equipment is increased.
