摘要 随着新能源技术的发展,偏远山区、海岛等独立电力系统越来越多地采用新能源发电设备与柴油发电机混合供电方式。针对这类系统中新能源逆变器单独供电、与柴油发电机并联供电的功能需求,以逆变器单独供电时采用电压源控制、与柴油发电机并联时采用电流源控制为基础,提出基于逆变器控制模式切换和柴油发电机准同期并联相结合的控制策略,解决逆变器与柴油发电机并联过程的控制问题,电磁暂态时域仿真和1∶1样机物理实验验证了该控制策略的有 效性。

Abstract:With the development of new energy technology, more and more isolated power systems located in remote mountainous areas start to use both new energy generators and diesel generators as power supply. These power systems have the functional requirements for new energy inverters supplying power independently and diesel generators in parallel power supply. When supplying power independently, the new energy inverters run in voltage source control mode, while they run in current source control mode in parallel operation with diesel generators. Based on these features of the system, this paper proposes a control strategy combining inverter mode-switching and quasi-synchronization in parallel operation with diesel generators. The strategy solves the problem in the control of inverters and diesel generators parallel operation. It is verified through electromagnetic transient time-domain simulation and physical experiment on 1∶1 prototype.
