is the DC-grid voltage.

... When realizing a local DC-voltage grid, an appropriate choice of the voltage level is important. When using a higher voltage level, the current will be lower in order to supply the same required power. This implies the voltage drops decrease and also the power losses in the grid conductors decrease ...

The voltage will be the least distorted nearest to its generating source and will become more distorted nearer to the load, as the harmonic current flows through larger amounts of impedance. If the load in Fig. 1 draws harmonic current, the highest level of v ...

Electrical substation



A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control.A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. The word substation comes from the days before the distribution system became a grid. As central generation stations became larger, smaller generating plants were converted to distribution stations, receiving their energy supply from a larger plant instead of using their own generators. The first substations were connected to only one power station, where the generators were housed, and were subsidiaries of that power station.
