| 摘 要： | 针对大型公共设施内2台备用柴油发电机组单机运行和并联运行分别进行仿真,计算在不同启动方式下发电机的冲击电流、电压、功率瞬变和启动稳定时间等,分析其特点,据此提出两柴油发电机组应急启动方式.分析认为,两/多台柴油发电机并联运行有利于维持发电机在高效率工作状态,保证了供电的可靠性和连续性,提高了适应负载变化的能力.作为备用电源投入时应先分别带负荷,再进行准同期并列,以提高应急响应速度.

| Abstract: | Two backup diesel generators＇ independent and parallel operations in large public facilities are analyzed respectively by simulation. Based on the characteristics of the current impact, voltage, power transients and startup stabilization time in different ways, the startup mode of the emergency diesel generators are proposed. In conclusion, parallel operation of the standby diesel generators can help maintain high efficiency, reliability and continuity for power supply and improve the applicability for load changes. As emergency power, the diesel generators may feed load respectively first and then juxtapose so as to increase response speed. |
