6 FAQs about [Dc supply system in power plant]

How many DC systems can a power substation have?

A power substation can have one or several DC systems. Factors affecting the number of systems are the need for more than one voltage level and the need for duplicating systems. Today, normal DC auxiliary supply systems in power substations are operating either on the 110 V or 220 V level, though lower levels exist.

Why do substations need a DC power supply?

This output can be utilized while making a battery discharge test during substation commissioning or regular maintenance and testing. Since the DC system supplying specially relay protection, control, and interlocking circuits is of paramount importance to the substation’s reliable and safe operation, the energy supply has to be always available.

What voltage is a DC auxiliary supply?

Today, normal DC auxiliary supply systems in power substations are operating either on the 110 V or 220 V level, though lower levels exist. Some systems at the substation may require lower voltages as their auxiliary supply source.

What is an AC/DC power supply?

The main job of an AC/DC power supply is to transform the alternating current (AC) into a stable direct current (DC) voltage, which can then be used to power different electrical devices. Alternating current is used to transport electric power all across the electric grid, from generators to end users.

How does a DC power supply work?

A basic DC power supply may be built with four sections with each one representing a specific circuit performing a unique task. It consists of different parts such as a transformer, rectifier, filter, and regulator. An AC signal is provided as an input to the transformer which is generated using a line voltage like power from an electric outlet.

What voltage auxiliary supply system is used in power substation?
