摘要： A circuit arrangement is for operating a load having a reactive characteristic on an AC power supply. The circuit arrangement enables the best possible reactive power compensation, that is, enables operation close to a cos θ of 1, in order to increase the overall efficiency of the arrangement or to achieve optimal energy savings. In order to control critical operating states, a feedback loop is provided that supplies a control current to a further reactive circuit element. This further circuit element is arranged parallel to the load or to the power factor correction capacitor, and is acted upon by a control current such that the control current counteracts a change in the reactive component of the load. The control current is derived from the load current as a variable proportional to the load current. In this way, a reactor for optimizing electromagnetic consumption is created.

摘要： An apparatus and a method for reactive power compensation of a test transformer with an inductor and a stepped capacitor bank and a generator. The generator is used for generating a generator current and a generator voltage with a predeterminable test frequency. The inductance of the inductor can be set and can be interconnected with a stepped capacitor bank in such a way that the generator can be operated on virtually exclusive active power. Within the test circuit, the generator is therefore almost always set at an optimum operating point for testing of the test transformer and does not need to be dimensioned to be any larger than required. As a result, the power of the generator can be used in optimum fashion for generating the generator voltage and, as a result of the reduction in the component part sizes which is carried out on the essential components in the test circuit, enables the mobile use of the entire apparatus for in-situ testing of the power transformer to be tested.

摘要： According to one embodiment, there is provided a substation automatic control system. An automatic power adjusting apparatus activates an automatic voltage adjusting apparatus when a phase tap is controlled. The automatic voltage adjusting apparatus activates the automatic power adjusting apparatus when a voltage tap is controlled. The automatic power adjusting apparatus suppresses the effective power on a transmission line to the value smaller than the prescribed value while the automatic voltage adjusting apparatus is performing an automatic control, thereby maintaining transmission-side system voltage within a tolerant system voltage range.
