Hydraulic power plant valve operation intelligent management system and method

Abstract

The invention discloses a hydraulic power plant valve operation intelligent management system which comprises an operation management host, a communication adapter, a plurality of computer keys and aplurality of electronic coding chain locks which are in communication connection in sequence, and the operation management host comprises a man-machine interaction module, a communication module and adata service unit. The data service unit comprises a valve anti-misoperation rule database, a valve operation rule database, a typical operation ticket library, a lock electronic code library and a valve operation history library. The intelligent management method for the valve operation of the hydraulic power plant comprises the following steps: 1 checking a system; 2, confirming a valve to be operated; 3, simulation operation; 4 unlocking the electronic coding chain lock; 5, valve operation; and 6, returning data. The valve locking device has the advantages of being high in valve locking efficiency, capable of preventing misoperation and high in automation degree.

Description

technical field [0001] The invention belongs to the technical field of valve operation management, and in particular relates to an intelligent management system and method for valve operation in a hydropower plant. Background technique [0002] There are many equipment and instruments installed in the hydropower plant, including a large number of mechanical valves. These mechanical valves operate frequently during the power generation process of the hydropower plant, and often open, close, and operate in the wrong order. It will cause serious safety accidents such as water leakage, high-pressure steam, and water injury. At present, there are the following problems in the operation of valves in hydropower plants: First, when operating the valves, the operating personnel check the paper operation tickets. The labor intensity of the operating personnel is relatively high, and the correctness of the valve operation largely depends on the operating personnel. Due to the large nu...

Problems solved by technology

[0002] There are many equipment and instruments installed in the hydropower plant, including a large number of mechanical valves. These mechanical valves operate frequently during the power generation process of the hydropower plant, and often open, close, and operate in the wrong order. It will cause serious safety accidents such as water leakage, high-pressure steam, and water injury.

At present, there are the following problems in the operation of valves in hydropower plants: First, when operating the valves, the operating personnel check the paper operation tickets. The labor intensity of the operating personnel is relatively high, and the correctness of the valve operation largely depends on the operating personnel. Due to the large number of valve operation items during maintenance and isolation operations, it is easy to skip items, miss items or misoperate during operation; secondly, when using paper operation tickets, it is easy to be polluted by on-site oil pollution, and also It is easy to be damaged, which is not conducive to long-term use; third, during maintenance and isolation operations, the valves in normal operation and the valves in the maintenance area are often close to each other, or even together. Fourth, the current operation and management of valves only regard mechanical valves as independent individuals, without effective management of the logic and sequence of operation between valves, and valve maintenance cannot be well realized Isolation; Fifth, the traditional valve locking needs to carry locks, the number of locks is large, the weight is heavy, it is not easy to carry, the operation is inconvenient, and the valve locking efficiency is low
