As the technical requirements for distribution network stations become more complex there is a growing demand for power distribution solutions and energy efficient designs. The Compact Secondary Substation (CSS), equipped to cope with changing distribution network sections, is a key installation in the power grid.
CSS is a prefabricated secondary substation with type-tested equipment, and it includes a distribution transformer, medium voltage switchgear, low-voltage switchboard, connections and associated equipment in a compact unit. The enclosure is typically divided into three sections or compartments – medium voltage switchgear, low voltage switchboard and distribution transformer. As these substations are usually installed in locations accessible to the public, they offer improved safety to utility personnel and members of the public, alike.
CSS is used for energy transformation in secondary distribution networks from medium voltage (MV) to low voltage (LV) or LV to MV systems. ABB prefabricated substations are versatile; they can be monitored, controlled or even support complete network management to offer complete reliability to power providers.
A CSS offers specific benefits over a conventional substation − enhanced reliability of power distribution, safety and space saving solutions
ABB in India has been a regular supplier of CSS solutions to its various clients. In 2009, ABB supplied 33 kilovolt (kV) CSS to evacuate power from a wind farm project in western India for Ghodawat Industries (India) Pvt. Ltd. This was the first time a CSS was used for this purpose, presenting new possibilities in wind power evacuation.
Recently, in March 2012, ABB delivered solar solutions for Tata Power’s 25 megawatt (MW) photovoltaic solar power plant at Mithapur in Gujarat. ABB supplied various products and solutions for this project, including SCADA, inverters, main junction boxes, PLCs, medium voltage switchgear, transformers and a distribution substation, including CSS. This is one of the largest grid-connected solar power plants in India.
ABB offers compact secondary substations for power distribution as well as evacuation of power from photovoltaic based solar power plants.
