Electricity Transmission

Electricity Transmission scenario in India

India?s electricity transmission industry is at cross roads. From a huge coal based electricity generation it is moving to generate electricity from renewable energy of solar and wind. These energy are not reputed to provide accurate forecast and hence it becomes all the more challenging for the power load centres. The transmission grid has to be smart and adaptable to meet the surging energy demand and supply from all kinds of power generation . There will be wide variation in terms of supply - seasonal, day and night as well as in demand with huge penetration of air conditioners, rural farmers agri power needs and increasing industrialization. The demand for electricity is on the rise following the GDP growth. The decision of system operators in SLDCs, RLDCs and NLDC greatly depends on t

Emerging technology in Grid Management

India has one of the largest synchronous grid in the world which is also expanding at rapid space. There is increasing mix of renewable energy like wind and solar power which are notorious for fluctuation in generation of power. With increasing renewable energy, there is wide variation in generation as well as loads on daily/seasonal basis, multi direction flow of power, open access, unscheduled interchange (UI) and the need for economic dispatch. Currently, regional dispatch centre receive data at regular intervals of 4 second to 15 second. However, they are of steady state value, while we need to monitor change dynamically. To overcome these challenges, we need to bring smart and intelligent grid which can provide 1. Integrated energy and Communication system architect; 2. Phasor mea

Should we go for 1200 kv stations ?

With a need to meet the rising challenges of unbalance growth in renewable energy and distant power generation centre, there is a need for high density transmission corridors. It has to be done either by increasing voltage level or current. However, there is a limit where we can increase the capacity (MW) per metre without reaching high voltage. Currently, in India we have high voltage corridor upto 765 kV and PowerGrid Corporation has deployed a 1200 kv sub-station as a test station in Bina in Madhya Pradesh. It may be noted, the world over very few countries like Russia, USA and Italy have tried high voltage transmission lines at 1200 kv. Crompton Greaves has successfully developed their first 1200 kV product. and is now successfully deployed in 2016. The project was conceived in 2009 a
