PURPOSE:To perform stable systematic power transmission by setting the voltage marker of a generator in a power line system variably according to the value of bus line voltage, when voltage detected from the bus line of a trunk line system substation in the power line gets out of a previously set value. CONSTITUTION:Based on bus line voltage signal 2 detected from the trunk line system substation 1 of bus line voltage Vs, generator voltage regulation signal Vref is created and the output of regulating signal 4 is generated, and it is transmitted to a signal receiving circuit 6 via a signal transmitting circuit 5. The marker voltage signal Vref of generator voltage and the received regulating signal Vref are added to each other to from signal 7. Generator voltage signal Vt detected from a generator 11 by a PT9, and the signal 7 are subtracted from each other to find signal Vt, and by an automatic voltage regulator 8, signal to a field coil 10 is regulated. As a result, the voltage fluctuation of the bus line of the trank line system substation is reguated by the generated voltage of the generator, and the systematic execution of high reliability is realized. |
