insufficient or sufficient reactive power and low power factor of power grid are existed
which affects safe and stable operation of power system.In this paper
the significance of shunt compensation technology in improving stability of power system is described by the authors
the principle of shunt compensation technology in improving system voltage stability is analyzed and a kind of typical TSC+TCR reactive generation model of reactive shunt compensation device is set up. Through switching appropriate number of TSC and TCR
the magnitude of reactive power injected the power grid is changed
and the function feature of TSC+TCR reactive generator is verified.
