前几年,河北省大城县供电局由于对无功管理认识浅薄,10kV线路上80年代投用的电容器,绝大部分因管理不善而损坏,致使全县平均功率因数仅为0.74.为了提高供电运营效益,我们从1994年起就制定了配电网电压和无功质量整治实施方案.加强无功管理,保证电能质量,减少线路及设备损耗,提高供电经济效益成为全局的工作重点.我们根据高压补偿和低相结合,以低压补偿为主;集中补偿和就地补偿相结合,以就地补偿为主的原则,研究
A few years ago, due to the poor understanding of reactive power management in Dacheng County Power Supply Bureau in Hebei Province, most of the capacitors put on the 10kV line in the 1980s were damaged due to poor management, resulting in an average power factor of only 0.74 in the entire county. In order to improve the power supply Operational efficiency, we have formulated the implementation plan of distribution network voltage and reactive power remediation since 1994. Strengthening reactive power management, ensuring the power quality, reducing the loss of power lines and equipment, and increasing the economic benefits of power supply have become the focus of the overall work. The combination of high-pressure compensation and low-pressure compensation is mainly based on low-pressure compensation. The combination of centralized compensation and on-site compensation is mainly based on the principle of on-site compensation.
