Consultancy & Design Engineering of EHV Electrical

Product Details:

Due to Climate change and International pressure, Renewable energy power plants are fast replacing conventional thermal power plants (coal or gas or oil fired). The most common type of renewable energy power plants are either Solar or Wind turbines. The power generated in these power plants gets interconnected / synchronised with the electricity grid through Extra high voltage Switchyards and Transmission lines. The existing Grid substation may also need extension of its EHV bays to accommodate termination of the Transmission line originated from the Solar / Wind farm substation. Satcon provides the following Consultancy services for the power system interconnection :

1. Visit to the existing Grid substation and checking feasibility of the proposed interconnection with the solar / wind power plant.

2. Electrical system study such as load flow, short circuit, transient stability study using ETAP software to check system parameters.
