Power plant steam turbine professional subsystem debugging plan debugging method

Abstract

The invention belongs to the technical field of power plant steam turbine debugging, and particularly relates to a power plant steam turbine professional subsystem debugging plan debugging method. Thepower plant steam turbine professional subsystem debugging plan debugging method is divided into a first-stage debugging stage, a second-stage debugging stage and a third-stage debugging stage, and specifically comprises the steps of BOP system preparation, cold source preparation, alkali washing preparation, blowpipe preparation and flushing rotation preparation. According to the power plant steam turbine professional subsystem debugging plan debugging method, by adding the mounting nodes and the mounting test to a steam turbine professional subsystem debugging plan and improving the sequence of more important mounting unit responsibility nodes and debugging unit responsibility nodes, the mounting operation and the debugging operation are prevented from being crossed, the mounting unit and the debugging unit can coordinate with each other, the debugging leads the mounting progress, and the mounting promotes the debugging progress. According to the power plant steam turbine professional subsystem debugging plan debugging method, through a three-level debugging plan, all nodes are subjected to hierarchical management according to the influence degree of each node on upstream and downstream during subsystem debugging, so that the effects of shortening the total project period and saving the project time cost are achieved.

Description

technical field [0001] The invention belongs to the technical field of steam turbine debugging in a power plant, and in particular relates to a debugging method for a professional sub-system of a steam turbine in a power plant. Background technique [0002] Generally, the entire infrastructure construction cycle of a power plant in the power industry includes four major links: design, equipment manufacturing, installation, and commissioning. Among them, commissioning is the necessary adjustment and testing of the installed systems and equipment to make them meet the safety and quality requirements, and it is a key link to comprehensively inspect the design, equipment manufacturing and installation quality of the upstream power plant. [0003] The commissioning link can be divided into sub-section trial operation and complete start-up debugging, and the sub-section trial operation link includes single-unit debugging and sub-system debugging. The sub-system debugging is carri...

AI Technical Summary

Problems solved by technology

[0005] 1. Only the commissioning and testing nodes are considered, and the status quo of intersecting work between installation and commissioning is not fully considered, resulting in frequent interruption and restriction of installation and commissioning work, hindering the normal progress of their respective work;

[0006] 2. The setting of key milestone nodes for debugging is unreasonable and the priority is not prominent, resulting in unclear phased goals;

[0007] 3. The logic of sub-item debugging sequence setting is not strong, the connection and coherence are not strong, and the pre-order and follow-up operations cannot be clearly indicated, which often leads to urgent work and idle work, resulting in waste of human resources
