Method for automatically forming patterns in design of power system of thermal power plant

Abstract

The invention discloses a method for automatically forming patterns in the design of a power system of a thermal power plant, and belongs to the technical field of thermal power plant engineering design department power system design. The method comprises the following steps of: 1, establishing an interaction interface under a computer aided design (CAD) platform; 2, establishing standard electric equipment blocks; 3, defining the attributes of all the electric equipment blocks; 4, establishing CAD patterns of single devices in a power system deployment diagram; 5, establishing the CAD patterns of the single devices of a power system device list; 6, establishing the CAD patterns of the single devices of a power system terminal board outgoing line; 7, defining the standard format of a power system cable inventory; and 8, generating a finished product. By the method, the technical problems of power supply device missing, writing errors, finished product format non-uniformity and the like in the conventional power system design methods are solved.

Description

technical field [0001] The invention belongs to the field of power supply system design of a thermal power plant engineering design unit, and specifically relates to a method for automatically forming drawings for the design of a thermal power plant power supply system. Background technique [0002] AutoCAD is computer-aided design, which is a computer software that uses computers and graphics equipment to help designers carry out design work, referred to as CAD. [0003] Thermal power plant thermal control professional power system design is mainly divided into 380VAC and 220VAC power system. Among them, the design of 380VAC power supply system is divided into two design methods: intelligent integrated electric device and non-integrated electric device; while 220VAC power supply system includes electric equipment with power distribution only and electric equipment with control loop; The electrical equipment of the circuit is also divided into single electric control and do...

Problems solved by technology

[0011] In the traditional power system design method, the recording of electrical equipment information must be careful, a little negligence will affect all subsequent work, and rework may occur; in the screening process of electrical equipment, once the screening is wrong, the subsequent There will be a wide range of changes in the work; power system configuration diagrams, terminal block design, and electrical equipment table production will repeatedly fill in the equipment number and name, all of which are manually entered, and require one-to-one correspondence. requirements, but it also brings a lot of tedious and repetitive workload to the design work, and the error rate and finished product quality cannot be guaranteed

[0012] At present, in the design of the power system, there is still a way to associate the blocks in the CAD drawing elements with the database platform, store all the data in the database, and write the data into the template by pre-customizing the template, this method cannot be separated from the database It runs independently, and the finished product template is too limited, and the finished product drawn requires a lot of manual modification, which is not very practical
