摘要： PROBLEM TO BE SOLVED: To correctly judge whether the reverse power is at a consumer terminal or at a main and back-up load system at the time when a breaker of a transformer station for a power supply is opened, by discriminating the consumer terminal reverse power detection characteristics of a spot network system by using the line power or a quantity of electricity obtained by subtracting the average power from the line power. SOLUTION: A line power calculating means 421 calculates the effective power Pi and reactive power Q1 for each line from each line current and line voltage. Then, an average power calculating means 422 calculates the average power of all the lines obtained by the line power calculating means 421. Then, a discrimination power judging means 423 calculates the discrimination power for earth line constituted of a difference between the power obtained by the line power calculating means 421 and the average power obtained by the average power calculating means 422, and then a reverse power judging means 424a applies the discrimination powers to the operating conditions for five relay elements to judge whether the power is reverse power or not. By this method, the reverse power at the consumer terminal and the reverse power at a main and back-up load system at the time when a power supply terminal is opened can be discriminated from each other.

摘要： PROBLEM TO BE SOLVED: To provide a distribution line voltage variation compensator which reduces the size of a static var compensator, and facilitates its assembling. SOLUTION: A step voltage regulator (SVR) 3 for a line and a static var compensator (SVC) 4 are connected to a distribution line 2. The SVR is caused to perform adjustment operation, so as to make distribution line voltage within a dead zone. The upper limit value for a control target voltage larger than the upper limit of the dead zone of the SVR, and a lower limit value for the control target voltage smaller than the lower limit value of the dead zone of the SVR, are set for the SVC. When the distribution line voltage of the installation point of the SVC is increased and decreased, adjustment operation is performed, which returns the distribution line voltage to the upper limit value and the lower limit value instantaneously, by injecting reactive current from the SVC to the distribution line, respectively. With the progress of the voltage adjustment operation by the SVR, a quantity of voltage compensation is transferred from the SVC to the SVR, and the output of the SVC is made zero, before the compensation operation is completed.

摘要： PROBLEM TO BE SOLVED: To control exciting inrush current of a transformer connected to the output side of a power inverter. SOLUTION: An equation 1 is fulfilled where a magnetic flux of the transformer is ϕ, an initial magnetic flux is ϕ0, number of turns is N, and a voltage applied to the winding is U(t). When voltage of U(θ)=Vmsinθ is applied with the initial magnetic flux ϕ=0, the magnetic flux is expressed by an equation 2. According to the equation 2, when a phase for generating voltage is set to the time of 90 deg. or 270 deg. to a sinewave, the exciting inrush current of the transformer can be controlled. A 90 deg. or 270 deg. pulse signal is generated with a sine wave table 11, and an output voltage command is sample-held with the pulse signal with a sample-and-hold circuit 14 and multiplied by the sinewave from the table 11 with a multiplier 15, thus it is possible to generate the voltage output command voltage at 90 deg. or 270 deg. to control the power inverter.
