摘要： 针对港口岸桥负荷冲击对发电机组的影响,开展基于磁悬浮飞轮储能阵列的岸桥微网控制系统研究。采用飞轮阵列快速储能和释能优势,用于平抑岸桥负荷冲击,保持发电机组的理想加减载运行需求。介绍了微网控制系统组成和飞轮阵列充放电原理,给出了飞轮单机系统模型。在分析岸桥负荷特性和发电机组的加减载特性基础上,针对飞轮阵列系统的容量配置和控制策略进行了设计,提出了一种基于飞轮剩余电量和发电机组预期加载特性的飞轮充放电控制功率计算方法。以实际岸桥运行数据为依据进行了仿真分析,结果表明,该岸桥微网控制系统可长期稳定运行,飞轮阵列能有效平抑岸桥负荷的功率冲击。为了验证了飞轮阵列的协同控制特性,进行了飞轮对拖充放电实验测试,结果表明,飞轮阵列的响应特性、容量和功率均能满足岸桥微网系统设计需求。

Abstract: For the influence of a sudden port-shore loading on the generators, the magnetically suspended flywheel-array-based micro-gird control system was studied. Due to the priorities of fast energy storage and release, the flywheel array can be able to reduce the power shock of the shore devices such that the ideal loading requirement of the generators can be obtained. The composition and working principle of the micro-grid control system were introduced with the mathmatical model of one single flywheel system provided in detail. Through analysis on the characteristics of the shore loading and generators increment-discrement loading output, the capacity and control strategy of the flywheel array were designed. A kind of charging-discharging power calculation method was proposed based on the combination of the residual flywheel energy and prebefore loading performance of the generator. The simulated system model was established and the results were given through the simulink tool, by using the real port-shore operation data. The simulated results were presented that the designed micro-gird system can be continously effective to reduce the power shock of the shore load. Some multi-driven experimental tests were developed to demonstrate the cooperative control performance of the flywheel array. It is shown that all of the response speed, capacity and power can be able to satisfy the design requirement of the port-shore micro-grid system.

Key words: port-shore load shock, magnetically suspended flywheel energy storage array, fast energy storage and release, charging-discharging control strategy
