柴储独立供电系统的功率协调控制策略

Power Coordination Control Strategy for Diesel Power Storage Independent Power Supply System

在利用柴油发电机组系统作为直接供电方式的一些地区,常规柴油机发电系统会由于负荷轻重的不稳定,而导致供电系统的工作状态也会因此不停波动。鉴于此种情况,提出了一种相对有效的优化方案,在发电系统中引入了储能电池和功率控制装置,用来协调控制整个供电系统的能量流动:在负载很轻时,储能电池独立逆变进行供电;负载较重时,以发电机的输出作为交流母线系统,储能电池和柴油发电机并联供电;当储能电池电量不足时,和用电负载一起作为系统的负载,发电机对其进行充电,从而确保柴油机发电系统能够高效稳定地工作。

In the use of diesel generator system as some areas of direct power supply mode, conventional diesel power generation system due to the severity of the load was not stable, resulting in power system state would therefore stop fluctuations. In view of this situation, a relatively effective optimization scheme in power system was introduced in the energy storage system and a power control device, the flow of energy to the coordinated control of the power supply system： when the load was light, the energy storage system of inverter power supply ; the load was heavy, with the output of the generator as the communication bus system, storage batteries and diesel generators parallel power supply ; when the storage battery was low, and the electric load as the load of the system, the generator to charge, so as to ensure that the diesel engine power system could stable and efficient work.
