Popis: | The voltage level matter, in power distribution networks, has a great importance due to the effect which an improper voltage may have over the electrical users. A higher voltage level may determine a shortened equipment life, while a low voltage level cause the increasing of the current network which leads to equipment failure. The voltage variation limits in distribution networks are imposed by standards in force. Performance Standard of Electrical Distribution Network stipulates the following: “In the delimitation point, in normal working condition, the effective mean value of delivered voltage within 10 minutes in 95% during any period of a week should not have a deviation greater then ±10% of contract voltage for MV and HV respectively ±10% of nominal voltage for LV. “Voltage decrease outside the limit of -10% is one of the most common deviations in distribution networks, causing penalties charged to the distribution operators. Thus, voltage increasing, for them where this is necessary, is an important concern for the distribution operators. This work aims to treat the increasing voltage level solution in low voltage networks using capacitors to compensate reactive power flow. |
