Electrical substation

Substations do not (usually) have generators, although a power plant may have a substation nearby. A typical substation will contain line termination structures, high-voltage switchgear, one or more power transformers, low voltage switchgear, surge protection, controls, grounding (earthing) system, and metering.

such as remote generators with voltage regulators that will maintain their value regardless of the presence of a short-circuit on the system, as well as nearby sources whose voltage will decay when the short-circuit is present. The amount of decay is determined by the nature of the source. Nearby generators and synchronous motors which have

Earthing Transformer

(VII) Earthing transformer. The earthing transformer has two separate windings on one limb which are represented in the circuit diagram by parallel branches. Neglecting the magnetizing currents it will have infinite impedance for positive- and negative-phase sequence currents. For zero-phase sequence currents the ampere turns due to each winding on the same limb cancel, and the

Substations

When substations were first installed, they were considered to be directly associated with a single generating station; hence the name substation was used, and the name remains to this day.. The first power generators in the 1870s and 1880s were direct current systems; transmission of electricity over long distances was therefore not feasible, and generation was generally placed

6 FAQs about [Generator substation selection]

Where should a Generator Substation be located?

A generator substation will obviously be located near or adjacent to the actual generator, although there may be situations where a site is chosen so that the substation is located away from sources of pollution such as dust or sea spray that might be adjacent to a power station and detrimental to future substation performance.

How do you design a substation?

Design of substations [11.14] involves a range of considerations, from site selection, to substation layout with adequate redundancy, electrical clearances, insulation coordination, structural and civil design, and secondary and auxiliaries design.

How does a substation design and equipment selection work?

Stay tuned for a comprehensive post on substation design and equipment selection. Once the planning and design phases are complete, the substation moves into the construction and implementation stage. Effective project management, quality control, and safety measures are key to successful construction.

What are the main electrical connections in substations and switchgear installations?

Main Electrical Connections: The electric power in substations and switchgear installations is received and distributed by means of the main bus-bars to which the equipment is connected according to some given main circuit scheme. It is necessary to distinguish two fundamental types of power station and substation circuit arrangements:

What are the design considerations for a new substation?

One of the fundamental design considerations for a new substation is the environment. The environmental conditions that exist at the new site must be considered in designing the infrastructure, but the designer must also consider the impact of the new substation on the environment once built.

How to choose a substation site?

Availability of Suitable and Sufficient Land: The land proposed for a substation should be normally level and open from all sides. It should not be water logged particularly in rainy season. The site selected for a substation should be such that approach of transmission lines and their take off can be easily possible without any obstruction.
