“…The main topology of Static Var Generator is a three-phase bridge inverter. By controlling the output voltage of the AC side or adjusting the output current of the AC side, the device can output advanced reactive power or lagging reactive power [1][2][3]. Compared with traditional reactive power compensation devices, SVG has the advantages of small volume, low loss, large adjustable range, fast response speed and low harmonic content [4][5][6].…”

With the strategy of constructing new power system with new energy as the main body put forward, the installed capacity of new energy in Hunan area will usher in explosive growth during the 14th five-year Plan period. The safe and stable operation of new energy stations to power grid will also be increasingly intensified. The paper briefly introduces the working principle, working mode and application of SVG(Static Var Generator) device supporting new energy stations. Based on relevant standards, a test scheme suitable for new energy stations in Hunan province is proposed. Taking the SVG device supporting a new energy station in Hunan province as an example, the grid-connection performance test is carried out to comprehensively and scientifically evaluate the network-related performance of SVG devices in the new energy station.

Thermographic Measurement of the Temperature of Reactive Power Compensation Capacitors

An excessive increase in reactive power consumption is unfavorable from the point of view of a power system. For this reason, devices compensating reactive power consumption are used. The capacitor is one such device. Capacitors must be tested regularly during their exploitation. One of the activities that should be performed is testing the degree of heating of the cells of a capacitor bank. Thermography can be used to perform such tests. This non-contact method has its limitations. Due to the angular emissivity and the change in the distance between the lens and the object under observation, the temperature measured with a thermographic camera may differ from the actual temperature. This phenomenon is visible on cylindrical capacitor cases. Consequently, depending on the location of the observation point on the capacitor case, the result of the thermographic temperature measurement may be different. To investigate this phenomenon, experimental work has been undertaken.

In this paper, a novel approach to matrix-converter-based variable frequency drives is presented. It is proposed that these drives are used to provide or draw out reactive power from the power distribution line, keeping the power factor close to unit and, simultaneously, performing their primary function of motor powering and speed control. This application of matrix-converter-based variable frequency drives is required due to the need to compensate for capacitive reactive power generated by light emitting diode lighting devices. In this study, the reactive power compensation range of the matrix-converter-based variable frequency drive is determined, and a method is proposed to extend the compensation range.
