摘　　要：城市电缆的广泛应用带来了大量的充电功率,导致电网无功功率充裕甚至过剩,引起系统电压偏高,在小负荷方式下其影响尤为明显。讨论了电缆充电功率的理论计算,并结合具体实例分析了小负荷方式下电缆充电功率对电网无功平衡及电压控制的影响,最后提出了加装感性无功补偿装置等控制措施的建议。The widespread use of urban cable has brought plentiful supply of charging power,causing sufficient or even excess reactive power and high system voltage,which is especially obvious during the light load period.In this paper,the theoretical calculation of the cable charging power is discussed in detail.Combined with concrete examples,the influence of cable charging power on reactive power balance and voltage control in the light load period is analyzed.Finally,the suggestions of control measures such as installing inductive reactive power compensation device are put forward.
