Intelligent generation method of program-controlled wiring diagram for coal transportation in thermal power plants

Abstract

The invention discloses an intelligent generation method of coal conveying program control wiring diagrams of heat-engine plants, and the intelligent generation method is used for design of electrical engineering and thermal control engineering of heat-engine plants. The method is based on the technical content of design of the electrical engineering of heat-engine plants and the computer technology, VC++ serves as a design platform, media boards of the bidding number are evenly distributed to program control cabinets by calling AutoCAD software and calculating the number of media boards of a program control master station and remote stations, the arrangement sequence of the media boards of the measurement points in each program control cabinet is set, and the wiring diagrams of the program control cabinets, coal conveying motor inventories of the remote stations and an integral coal conveying motor cable inventory are generated by judging whether the measurement point distribution of the measurement points in the program control stations and configuration of the media boards of the program control cabinets are reasonable or not. By the adoption of the method, the design efficiency and accuracy of the coal conveying program control wiring diagrams can be improved by more than 70%, and the design period is remarkably shortened.

Description

technical field [0001] The invention relates to the field of electrical and thermal control professional design of a thermal power plant, in particular to a method for automatically generating a program-controlled wiring diagram for coal transportation and a cable inventory. Background technique [0002] At present, most of the fuel used in large thermal power plants in my country is coal. The main tasks of the coal handling program control system in thermal power plants are coal unloading, coal stacking, coal loading and coal blending, so as to provide coal for units (or raw coal bunkers) on time and in good quality and quantity. The entire coal handling control system is a very important support system for thermal power plants, and it is an important condition to ensure the stable and full-load operation of the unit. [0003] In the design work of thermal power plants, with the increasing capacity of generating units and the continuous improvement of automation level, the...

Problems solved by technology

The current method of designing the wiring diagram is: manually compare the existing cable inventory, and fill in the label name, Chinese description, cable number, circuit number, cable destination, etc. of each measuring point one by one in the Excel table. The current design method is mechanically repetitive and extremely efficient. low, high error rate

With the large-scale construction and development of my country's electric power field, the requirements for shortening the design period are further increased, and the existing drawing methods can no longer meet the requirements of the "three major controls" of design progress, quality and cost.
