Weβre delighted to announce that Power Projects has been awarded a detailed EMI/EMC Study involving Radio Interference Analysis for 400 kV STATCOM substations in Southern India. This project is a crucial step in strengthening Indiaβs transmission network under the PGCIL System Strengthening Scheme, ensuring that high-voltage assets meet international standards for electromagnetic compatibility (EMC) and operational reliability.

High-voltage installations such as Β±200 Mvar STATCOM systems generate fast-switching transients that can cause electromagnetic interference (EMI), leading to radio noise, communication disruptions, and reduced insulation life. The objective of this EMI/EMC Study is to accurately quantify and mitigate these emissions to achieve compliance with CISPR 18, NEMA 107-1987, and relevant PGCIL specifications for Radio Interference Levels (RIL).
Using advanced ANSYS HFSS simulations, our engineers will model the electromagnetic field emissions from valve halls and assess the shielding effectiveness of various mesh geometries and materials. The analysis includes validating attenuation performance across 0.15 MHz β 300 MHz frequency bands and optimizing earthing and bonding designs to minimize radiated and conducted noise.
