Investigation of Voltage Drop in the Primary Distribution Network of Ghazni City and Voltage Regulation in That Network

The medium voltage feeder of Ghazni city, feeding the subscribers of Ghazni city, has a peak load of 4.5MW. Voltage drop in the network limits the transmission power and increases the transmission power losses. All electrical appliances are designed to work at a certain voltage and at the same voltage can do their normal work. Voltage is one of the basic parameters of the regime in electrical cycles that must be kept constant to the necessary extent for the subscriber. Excessive voltage fluctuations, both up and down, can cause damage to consumers. The purpose of this study is to investigate how the voltage drops and voltage regulates in the 20kV distribution network in Ghazni city. In this research, real field figures obtained from Ghazni Breshna Company have been used in voltage drop calculations. Voltage drop in the primary distribution network of Ghazni city is in the range of 5.7%, which is the highest Losses compared to the standard. IEC60204-1 (Protection of Electrical Machinery and Equipment), which recommends in Section 5-13 that voltage losses from the supply point to the electrical load point should not normally exceed 5% of the rated voltage, indicates a 0.7% increase in voltage drop. Voltage failure in addition to the negative monetary effect reduces the quality of electrical energy.
