摘要:
随着人民生活水平的不断提高,家用电器和农用机具已成为农村家庭的标准配置,使得农村用电负荷大幅增加。然而,与用电负荷快速增长不相匹配的是农村电网的发展仍相对滞后,农村电网的低电压问题十分突出,严重影响了人民的正常生活和工作。10 kV线路调压器在农村电网低电压治理中应用效果较好、成本较低。通过分析调压器工作原理,建立带10 k V调压器的配电线路等值电路,开展了调压器在10 kV线路中的理论计算,并结合农村线路实际情况进行了调压器的安装效果验证,为农村电网低电压治理工作提供参考。
Abstract:
With the continuous improvement of people＇s living standard，household appliances and farm machines and tools have become the standard configuration of rural households，which causes a huge increase in rural power load． However，the development of rural power grid is still relatively lags behind，which does not match with the rapid growth of electricity load， and low voltage problem of rural power grids is very outstanding，which seriously affects the normal life and work of people． Applying voltage regulator to 10 kV line of rural power grid is an effective method for low voltage control with good effect and lower cost． The working principle of voltage regulator is analyzed，and through establishing the equivalent circuit of distribution line with 10 kV voltage regulator，the theoretical calculation of voltage regulator in 10 kV line is carried out． Combining with the practical situation of rural line，the installation effect of voltage regulator is verified，which provides a reference for low voltage control in rural power grid．
