摘要:随着国民经济的快速发展，工业对电力的需要也越来越迫切，对电能的要求也更高。所以与用户相关的供电系统非常重要。本设计根据某工厂的相关资料和实际情况，对该工厂的高压配电所供电系统进行设计。本设计主要是对工厂供配电系统的电气部分进行设计。
本设计首先根据工厂的资料对工厂的负荷进行计算，然后根据需要进行无功补偿。根据负荷的实际情况确定主变压器的台数和容量，从而确定主接线方案，再进行短路电流计算，以此为基础选择配电所的电气设备，之后再进行继电保护的整定与防雷与接地等。本设计选择在该厂设立总降压变电所先将电压降为厂区供电电压6kV，再由各车间变电所降为负荷所需电压。
本设计可以满足工厂供电安全、可靠、优质、经济的特点，并保证各车间电气设备的稳定运行，投资少，实用性高。

ABSTRACT:With the rapid development of the national economy, need of industrial electricity is also more and more urgent, the energy requirements are also higher. So the power system associated with the user is very important. This design according to the related data of a certain factory and the actual situation, the high-voltage power distribution on the factory power supply system design.
According to the design of the first load the data on factory factory were calculated, and then according to the need for wattless power compensation. Determination of main transformer number and capacity according to the actual conditions of load, so as to determine the main wiring scheme, then the short-circuit current calculation, as a basis for the selection of electrical equipment, and then the selection and setting of relay protection and lightning protection and grounding. This design choice in the factory set up the total step-down substation first voltage drop for the factory power supply voltage of 6kV, then reduced by the plant substation voltage needed for load.
The design result can meet the characteristics of the power plant safety, reliable, high quality, economy, and ensure the stable operation of the plant electrical equipment, less investment, high practicality.
