摘要： PROBLEM TO BE SOLVED: To minimize received power from a commercial power system, by operating to lower the revolutions command value in response to differential power when the received power has fallen below a target value of the lowest received power to reduce generating power of a generator, thereby accelerating control of the generating power. SOLUTION: If the received power detected by a received power detector 15 is larger than a target value of the lowest received power, an output of a subtracter in a correction signal generator 13 is positive. Thus, an output of a functional circuit becomes zero, and no correction signal is generated. If the received power becomes a target value or lower of the lowest received power, an output of the subtracter becomes negative, and a signal responsive to the value is outputted from the functional circuit. The correction signal is generated by a signal obtained by integrating the signal by an integrating amplifier, and a rotational speed command value of a governor 8 is reduced. Accordingly, the received power is recovered. The correction signal is increased until generating power is recovered to the target value of the lowest received power, and then maintained at its value after the recovery, and hence the received power can be held at the target value.

摘要： PURPOSE:To predict misfire precisely and simply by comparing the newest exhaust temperature with a prior exhaust temperature per cylinder, and judging that possibility of misfire is high when such a condition that the newest exhaust temperature is lower by a constant value or more than its prior exhaust temperature. CONSTITUTION:A misfire predict device is provided with a data temporarily holding means 2 for temporarily holding the detected data of an exhaust temperature sensor 1, a temperature data held by that time is outputted to a comparator 3 every time when a timing signal is outputted from a timing circuit 4, and also a new temperature data is held. In the comparator 3, an exhaust gas temperature data is compared with an exhaust gas temperature data which is taken just one time before timing signal at every time of inputting of the timing signal from the timing circuit 4. When a temperature deviation DELTAT is smaller than a constant temperature (about 20 deg.C), it is judged by a misfire predict judging means 5 that there is no misfire. On the other hand, it is judged that there is possibility of misfire when the temperature deviation DELTAT is larger than the constant temperature.

摘要： PURPOSE:To eliminate the necessity of a memory for storing a table by adding a result, obtained through dividing an output signal from a circular or elliptic function generator by an input signal, to an arc tangent function generator and finding out the phase angle of an I/O signal. CONSTITUTION:When a signal x1 of 0 to 5V is inputted to the input terminal A of the circular function generator 1, the value y1 of the 1st quardrant is outputted from a terminal C and the 4th quardrant value y2 is outputted from a terminal D by setting up 5V to a standard value '1'. An analog divider 2 divides the quardrant values y1, y2 by the input signal x1 to find out y1/x1 and y2/x1 and when the obtained values y1/x1, y2/x1 are inputted from the arc tangent function generator 3 to the terminal E, the phase angle theta of vector ¦x+jy¦ i.e., theta= tan (y/x), is outputted from a terminal F. The output is the operation of polar coordinate-like data. When the characteristics of a CMOS inverter are switched by using the generator 3 instead of the generator 1, an elliptic function is generated.

SOLUTION: In a power supply 100 for supplying power (AC power) from a power supply line L1 to a load 13, a control circuit 11 outputs an instruction for controlling a q-axis to a converter 6 when a current transformer 10 detects fluctuation of power on the power supply line L1, controls timing when the converter 6 is connected, and generates power for canceling higher harmonic waves by using a capacitor 7 and a reactor 4.

摘要： PROBLEM TO BE SOLVED: To obtain a starter for a generator for operating to supply power to a load in a short time by synchronizing a plurality of generators and operating them in parallel, by providing a synchronous closing unit for closing a circuit breaker in the order of satisfying synchronous closing condition by resetting at the time of starting a generator set. SOLUTION: When a power interruption has been detected, a start controller 21 closes reset switches 20a, 20b to reset rotational speed set values. If a prime mover is started, respective generators are operated by this frequency, and hence a synchronous point is automatically generated at a fast period. In the generator of the number in which starting is rapidly completed, a generator bus 18 is charged. Meanwhile, the generator of the number in which starting is completed later, is rapidly synchronously closed. Synchronous closing units 22a, 22b close breakers 7a or 7b to operate in parallel. Thus, the starter for the generator for generating a start signal after power interruption is detected to start a plurality of the prime movers for synchronizing them and for operating them in parallel to shorten an operation for supplying power to a load can be realized.
