Description
Technical Field
The invention belongs to the technical field of maintenance operation of power plants, and particularly relates to an isolation deduction model and an evaluation method.
Background
Along with the implementation of national energy strategy, the nuclear power industry is continuously and vigorously developed, and meanwhile, the requirements of the supervision departments on nuclear power safety are also higher and higher. The operation department is used as a direct responsibility department for safe and stable operation of the power plant, and needs to provide safety conditions for maintenance, maintenance and other works of equipment of the power plant by timely and accurately controlling states of a system, equipment, components and the like, so that production safety of the power plant in production preparation and operation stages is ensured. This working behaviour of the operating sector is called isolation and comprises in particular: operating a certain type of operation equipment, and cutting off or evacuating a working source; closing or opening equipment facilities and locking and prohibiting any operation on such equipment; hang tags, alert such devices to specific actions and conditions, etc. The plant facilities of the power plant must have the following conditions at the same time to be able to be used as isolation equipment: firstly, the work can be completely separated; secondly, the isolated state can be locked forcibly. Typically, before a maintenance work is performed, the work of creating a work environment for the maintenance is referred to as an isolation branding task; after the repair work is completed, the work of restoring the pre-repair state of the facility is called an isolation card picking task. The isolation card hanging task and the isolation card picking task are used as the preface task and the follow-up task of the work order task, and form the complete process of maintenance work together with the work order task.
During an annual overhaul of a power plant, it is often necessary to complete the implementation of tens of thousands of work orders in a short time, before the work activities are implemented, the personnel involved are aware of the training and power plant risk analysis results obtained from the operating experience and have prepared countermeasures against the problems that may be significant in order to reduce the potential risk. The information management system is simple, effective and human-considered to ensure timely contact, coordination, approval and management of work activities. During a work activity (e.g., attaching security tags), changes in device status to protect personnel, devices and environments are effectively managed, implemented and verified. Effective radioactivity and pollution control are implemented to maintain reasonable and feasible radioactive doses as low as possible, reduce radioactive pollution of personnel and prevent unnecessary solid radioactive waste. Knowledge of the radioactive environmental conditions prior to operation is sufficient to make appropriate decisions. Keeps good working conditions, adopts industrial safety production management, and realizes high-standard personal safety.
Most of the work orders relate to equipment isolation, but due to the fact that equipment facility states have exclusive characteristics in a certain period, the work orders are decided to be developed according to a certain plan, and the fact that the equipment states conflict in a certain period to affect development of related maintenance work is avoided. Therefore, the scheduling of the worksheets directly affects the overhaul schedule, and further affects the production benefits of the power plant. In order to ensure the rationality and high efficiency of work order planning arrangement during overhaul, the rationality of the current overhaul work plan can be checked through an isolated deduction model setting and conflict processing method before overhaul, the equipment state conflict type can be identified, and the overhaul work plan can be optimized by guiding planning, operation and maintenance departments.
