摘要
分析了洋山港桥吊电机冲击性负荷和在生产过程中频繁起停产生的电压波动和电网运行不稳定等问题。从系统角度分析桥吊电机频繁起停与微网供配电系统的特点,提出对桥吊电机进行系统综合控制和单元分组控制相结合的递阶控制策略,并进一步提出超级电容储能器对桥吊电机预起动电能补偿的控制方案,可有效减小桥吊电机对电网的冲击,降低电能损耗和对环境的影响。同时,该方案可以为其他领域微网系统提供借鉴作用。
The bridge cranes of Yangshan port at badly-impactive loads and frequently starting and stopping in the process of production was analyzed,which results including voltage fluctuations and increasing of harmonic content.By analyzing characteristics of bridge cranes motor frequent starts and stops and microgrids for distribution system,comprehensive control system and unit group control system combined hierarchical control scheme was propsed,further more,the super capacitor accumulator to the compensation of bridge cranes start control scheme was proposed,which can effectively reduce the impact from grid bridge cranes,and further reduce power consumption and pollution to the environment.By the mean time,this program set a template for other areas＇ microgrids systems.
