<p>The regulating system has reactive converters resp. coupled across each of the phase-to-phase voltages of the three phase power system for delivering a leading or lagging current to compensate for a load of varying reactance. The regulating system developes a first signal representative of the R.M.S. value of the positive sequence component of the R.M.S. values of the phase-to-phase voltages of the three phase power system at the critical area. - Second signals representative of desired voltage regulation levels of each of the phase-to-phase voltages of the three phase power are developed at the critical area. A member responsive to the two signals developes error signals for the regulating system which are used to hold the two signals in close correspondence if within a desired range of the reactive converters.</p> |
