摘要： PURPOSE:To increase the stable phase advance operation range of a synchronous generator by providing a differentiating output generator in parallel with a reactive power regulator, and adding the output of the output generator to the output of an automatic voltage regulator for controlling the field current of the generator. CONSTITUTION:The exciting power to a synchronous generator G is branched by an excitation transformer Tr, and supplied via power regulator AD. The reactive power generated from the generator G is detected through a current transformer CT and a voltage transformer PT by a reactive power detector QD, added together with output of a power setter 9R to a reactive power regulator AQR, thereby operating an operation motor 9M. The calculated result of the AVR to the new set value is supplied to the regulator AD. DC voltage is supplied from DC voltage power sources P, N through a relay contact 9La to the differentiating signal generator DF, and the differentiated voltage is outputted to a signal adder A. The added voltage is applied to the regulator AD, thereby increasing the stable operation range of phase advance operation range.

摘要： PURPOSE:To enable to continuously control a general load amount by connecting a quasi-load controlled continuously by a plurality of quasi-loads and an automatic load controller energized or interrupted by a switch controller at the output side of a generator. CONSTITUTION:The output of a generator 55 driven by a prime mover is supplied to a read load 64 and quasi-loads R1-Rn. A detector SA detects the output power from the rotating speed of the prime mover, the output side terminal voltage of the generator 55 and the load current, and outputs a control signal in response to the difference between the output power and the set power. A switch controller CB controls switches S1-Sn-1 by the control signal to energize or interrupt the loads R1-Rn-1, an automatic load controller ALC controls the load amount of the load Rn to compensate the insufficient load. In this manner, the general load amount can be continuously controlled.

摘要： PURPOSE:To eliminate the breaker by interrupting the output supplied from a voltage regulator to a field current control element in response to the power supply stop and start to a load. CONSTITUTION:A voltage regulator 14 outputs a field current target value in response to the deviation between a generator voltage and a set voltage, and a current comparator 15 outputs a binary operation signal in accordance with the magnitude of the field current target value and a field current. When a power supply start switch PB1 is closed, a relay 34 is energized, and a switch 52 of a preexciter 50 is closed. When the generator voltage is raised, a constant-voltage diode 26 is conducted, and a transistor 32 is interrupted. Accordingly, the output of a current comparator 15 is applied to a transistor 7, and the voltage of the generator is raised to the set value. When a power supply stop switch PB2 is closed, the relay 34 is deenergized, its contact 34b is closed, the output of the current comparator 15 is restricted to zero volt, and the transistor 7 is interrupted.

摘要： PURPOSE:To precisely control the starting current, the torque and the speeds of the induction motor by rectifying the secondary side output of the motor and supplying the rectified output through a chopper to a load. CONSTITUTION:When three-phase alternating currents are applied to the primary winding of the induction motor 10 to start the motor, three-phase alternating current of voltage proportional to the slip is taken place at the secondary winding 10a, is applied to a rectifier circuit 11, is rectified to apply a DC voltage corresponding to the three-phase AC voltage to the chopper 12. A pulse duration control unit 13 supplies a pulse corresponding to the set value by a variable resistor 14 to the chopper 12, and the chopper 12 produces an output to a resistor 15 to be thus consumed.
