Abstract: This paper analyzes the load characteristics and electrical equipment layout of the heat absorption tower of tower CSP station,and summarizes the wiring scheme and key points of panel cabinet layout of the electrical system of the heat absorption tower. The analysis results show that:1) Based on the load demand of the heat absorption tower,it is recommended to adopt the principles of on-site layout of the motor control center（MCC）and comprehensive utilization of uninterruptible power supply（UPS）,and typical electrical equipment layout schemes and factors affecting their layout are provided. 2) Based on the structural characteristics and maintenance requirements of the heat absorption tower,it has been determined that the electrical cabinets in the electrical distribution room of the heat absorption tower will adopt the "upward input and upward output" method,and the vertical cable channels adopts a single-layer ladder type cable tray with multiple rows of laying scheme.3) Based on the type and characteristics of cable armor,it is recommended to use steel wire armor for power cables inside the tower. This design scheme can effectively improve the rationality,reliability,and convenience of operation,maintenance,and repair of the electrical system of the heat absorption tower of the tower CSP station,and has important reference significance for the design of the electrical system.
