【摘要】 随着用电规模的不断扩大和用电结构的不断变化,以及变压器和电动机等大量感性负载设备的广泛使用,使得用电设备对无功的需求大幅上升,导致电网中无功功率的不平衡。通过分析配电网络无功补偿的原理和GPRS无线通信网络的组成和特点,设计出一套以GPRS无线通信为数据通道的无功补偿方案,以此来解决中低压配电网网损过高等缺点,极大地提高供电质量,实现电能传输的经济效益。更多还原

【Abstract】 With the continuous expansion of daily power consumption and the continuous change of power consumption structure,as well as the wide application of transformers,electric motors and other inductive load equipment,there is a significant increase in reactive power demand by utilization equipment which leads to an imbalance of reactive power in power grid.The theory of reactive compensation in distribution network and the composition and characteristics of GPRS wireless communication network are analyzed.A set of reactive compensation scheme is designed taking GPRS wireless communication as the data channel so as to solve the excessive network losses of medium-low voltage distribution network and other shortcomings,which has greatly improved the quality of power supply and achieved the economic benefits of electric energy transmission.更多还原
