摘要
电力网络系统中存在大量的非线性电力负荷,电网稳定运行面临着巨大的挑战。作为电力网络末端的配电网络,因其与用户直接相连且负载种类繁多,在运行过程中存在较大的能量损耗。提出一种基于无功补偿技术的配电网节能改善模型,首先对配电网的无功负荷和能耗特点进行了分析,以此为基础对配电网络能耗优化原则进行了阐述,并根据这一原则建立了配电网能耗优化的数学模型,最后完成了配电网节能改善模型的设计。实验结果表明,配电网节能模型中采用补偿技术有利于改善电网供电质量和降低能量损耗,缩短节能时间约11.07s,对配电网节能模型的设计具有一定的理论意义。
There are a lot of nonlinear power loads in power network system, and the stable operation of power grid is facing great challenge. As the end of the power network, the distribution network, because of its direct connection with the user and a wide range of load, there is a large energy loss in the process of operation. This paper proposes an improved model of energy distribution network reactive power compensation technology based on the distribution network reactive power load and energy consumption characteristics are analyzed, then expatiates on the principle of optimization of distribution network energy consumption, and establishes a mathematical model of energy consumption distribution network optimization based on this principle, finally completed the design of the energy distribution to improve the network model. The experimental results show that the energy saving model of distribution network with compensation technology to improve the quality of power supply and reduce the energy consumption, energy saving and shorten the time of about 11.07s, has a certain theoretical significance for energy-saving design model of distribution network.
