wind power plant
the output power of generator is always fluctuated frequently because of variable wind power. At present, the popular asynchronous wind generator (including doubly-fed type) needs to absorb parts of inductive reactive power to build magnetic fields, the paralleled capacitor banks can realize compensation, but the stepped switching capacitor banks can not meet fast and dynamic reactive power compensation demand caused by variable wind power, sometimes, if the capacitor banks can not meet reactive power compensation in time, the wind generator will absorb reactive power from the upper power grid, which will result in low power factor of upper power grid and then cause voltage fluctuation, so the state grid put forward the < regulations on state grid corporation wind farm grid access technology (amendment)> based on voltage fluctuation, flicker, frequency deviation, harmonics and lacking reactive power.
the svc of mcr can solve the above problems to meet the demand of utility.
secondary substation (66kv to 110 kv)
in the regional power grid, the stepped switching capacitor banks are used to compensate the system reactive power and increase the power factor. But they are only able to provide the capacitive reactive power, and unable to realize rapid and accurate adjustment according to the load variation, so sometimes they provide much more reactive power than the actual desired reactive power, which will result in over voltage of the bus bar and damage the electric equipment and destroy system stability.
