Parametric underground coal mine power supply design method

Abstract

The invention provides a parameter type underground coal mine power supply design method. According to the method, data of a tree structure is taken as a carrier. The method is used for axuilarily designing an underground power supply system and reasonably selecting power supply equipment. The method is characterized in that the method is characterized by comprising the following steps: constructing a basic data structure, constructing an electromechanical equipment database, a model selection calculation algorithm library and a mapping style template library, inputting motor parameter nodes,sequentially connecting low-voltage switch, transformer and high-voltage switch parameter nodes, calculating short-circuit current and voltage loss, forming a power supply system model and automatically generating an underground power supply system diagram and an underground power supply design report according to requirements. The method abandons a traditional method of recording underground power supply design by using a drawing, takes data of a tree structure as a carrier, does not relate to graph modification, reduces the workload, updates a model selection calculation result in real time,is safe and reliable, and has a good popularization value.

Description

technical field [0001] The application relates to the field of mine electromechanical technology, in particular to a parametric coal mine underground power supply design method. Background technique [0002] Electricity is the main energy source for modern enterprises, and all modern coal mine production machinery uses electric energy as direct or indirect power. The design of power supply system is an indispensable part of mine production, and the normal and safe operation of electromechanical equipment is an important part of mine safety production. Therefore, correct and reasonable power supply design and management methods are crucial to the smooth operation of electromechanical equipment, the safety and reliability of relay protection, and the high yield and high efficiency of coal production. Common power supply design methods in mines are mainly divided into paper-based manual drawing design methods, computer-aided drawing design methods (CAD, Computer Aided Design, ...

Problems solved by technology

[0015] Drawings are used as the carrier to store power supply design drawings. Once the drawings are drawn, they are not easy to modify and need to be redrawn. The workload is heavy, and the power supply system diagrams of underground central substations, mining area substations, and working faces often need to be drawn in different locations. In the drawing, the connection relationship is not intuitive
