Abstract: A transformer having an insulation system is presented. The transformer includes a magnetic core having an opening. Also, the transformer includes a plurality of primary windings disposed extending through the opening of the magnetic core. Further, the insulation system includes a first insulation substantially encapsulating the plurality of primary windings and impregnating spaces between the plurality of primary windings, and a second insulation disposed around the first insulation, where the second insulation has at least one of a predetermined dielectric strength and a predetermined thickness configured to isolate a first voltage signal in the plurality of primary windings from the magnetic core.

Abstract: Systems and methods for regulating the voltage at a point of interconnection of a renewable energy plant, such as a solar plant, with a grid are provided. A voltage signal indicative of the voltage at the point of interconnection can be received and filtered with a high pass filter to generate a filtered error signal. The high pass filter can block components of the voltage signal at a frequency less than a threshold frequency. A reactive power command for the renewable energy plant can be generated based on the filtered error signal. One or more inverters of the renewable energy plant can be controlled to output reactive power based on the reactive power command. A rejection module can be implemented to prevent adverse interaction with other voltage control devices. In addition, a reset module can be implemented to preserve dynamic reactive power range of the inverters.

Abstract translation: 提供了用于调节可再生能源工厂（例如太阳能发电厂）与电网的互连点处的电压的系统和方法。 可以接收表示互连点处的电压的电压信号并用高通滤波器进行滤波，以产生滤波后的误差信号。 高通滤波器可以以小于阈值频率的频率阻挡电压信号的分量。 可以基于经滤波的误差信号产生可再生能源装置的无功功率指令。 可以控制可再生能源工厂的一个或多个逆变器，以基于无功功率命令输出无功功率。 可以实施拒绝模块以防止与其他电压控制设备的不利相互作用。 此外，可以实现复位模块以保持逆变器的动态无功功率范围。
