Analysis on Higher Voltage of Power Grid in Pastoral Area of ABa

The situation about the higher voltage in the power grid of pastoral area of ABa Prefecture is investigated and analyzed.The main reasons are pointed out,that is,there is no reactor to absorb reactive power,the transmission lines are longer and the transmitted power is lower.The corresponding countermeasures and measures are proposed to improve reactive power balance and to raise the passing rate of voltage.It is also suggested to speed up the transformation of transmission network in order to ensure the se...
