Practice and Security Constraint Strategy of AVC in Vietnam Power Plant

    Abstract
  •   Introduction   The automatic voltage control （AVC） system is an important tool for reducing network loss， improving the network voltage quality， and ensuring secure and stable operation of power network as well as the power plant.
      Method  Since there was no special AVC device in Vietnam， practice of AVC based on the power plant Distributed Control System （DCS） was carried out， in which the information interaction with Vietnam Power Grid Dispatching Center， and the AVC on/off & security constraint logic in DCS had been established.
      Result  Effective regulation of reactive power – voltage has been realized， satisfying the technique requirement of Vietnam power network.
      Conclusion  Therefore， it can provide a reference for the realization of automatic voltage control in overseas power plant projects.
