Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of building power supply and distribution simulation training systems, and specifically relates to a semi-physical simulation operation training system for a building power supply and distribution system. Background Art
[0002] The power supply and distribution system is an indispensable and important link in the modern power supply system. It is responsible for safely and efficiently transmitting electric energy from the power generation link to various power-consuming equipment. The building power supply and distribution system refers to the entire circuit from the power supply line to the input end of the power-consuming equipment. Its main function is to receive, transform, distribute and transmit electric energy in the building. It is mainly implemented through substations and low-voltage side wiring. Substations are an important part of the building power supply and distribution system, used for transforming and distributing electric energy. The main equipment includes transformers and various distribution cabinets.
[0003] Therefore, the common main connection of the low-voltage side of the building power supply and distribution system includes single incoming line power supply, single busbar segmented power supply and ring network power supply. Different power supply methods involve different numbers and types of electrical equipment, different electrical connection methods between equipment, and different system operation procedures. At the same time, the outlet of the low-voltage distribution line is divided into three categories: trunk type, radial type and hybrid type. For loads with large single-machine capacity, relatively concentrated capacity, and high power supply reliability requirements, radial distribution is adopted, and power is supplied by a separate distribution line. For occasions where the power load is relatively uniform, the capacity is not large, and there are no special requirements, trunk distribution is adopted to connect the load to a distribution trunk line in sequence according to its location. The characteristics of trunk distribution are low equipment and cable consumption and good system flexibility. The comprehensive application of the two is called hybrid.
