This paper concerns a real-time control scheme of voltage and reactive power in power systems when more than two control computers as well as one central coordinating computer are involved. When a large number of voltage and/or reactive power regulating devices are involved in a power system and the number of nodes or lines in which the voltages or reactive power flows are observed and controlled increases, the necessary computing time and memory requirement increase exponentially if the central computer installed at the central dispatching office should take care of all control functions. In addition, the number of channels of the data transmission network becomes very large because the voltage and reactive power flow at each electric station must be transmitted to the central computer and the optimum operating values of regulating devices should be transmitted back to the regulating stations.
