Modern electrical power systems require substations that are reliable, efficient, and capable of supporting rapidly evolving grid demands. This presentation explores the key components involved in substation design, with emphasis on protection systems, control architecture, and engineering studies required to ensure system reliability and operational efficiency.

The session will discuss critical elements including substation layout design, protection and control schemes and communication infrastructure. 

Attendees will gain practical insights into modern substation engineering practices, protection coordination strategies, and design approaches that minimize energy losses while enhancing grid resilience.

Megha Bhardwaj  is an Electrical Power Systems Engineer with extensive experience in substation design, protection and control engineering, and power system studies. With more than a decade of professional experience in the power generation, transmission, and distribution sectors, the author has contributed to the design, analysis, and commissioning of high-voltage substations and power delivery systems.

The author has led protection and control engineering for multiple 69 kV, 345 kV, and 500 kV AIS and GIS substation projects, including development of protection one-line diagrams, AC/DC schematics, wiring diagrams, construction installation packages, and bill of materials. The role also involved coordinating with multidisciplinary engineering teams, managing technical documentation, and supporting project scheduling and engineering deliverables.

The author has extensive experience performing load flow studies, short circuit analysis, arc-flash studies, and protection coordination using ETAP, PSCAD, and SKM, along with conducting relay setting analysis and root cause investigations to enhance power system reliability. Earlier in the career, the author worked extensively in power plant commissioning, maintenance, and electrical system design, supporting the operation of large thermal generating units and participating in the commissioning of grid-connected solar photovoltaic power plants. The author’s technical expertise includes substation protection and control design, power system analysis, electrical construction documentation, and leadership of engineering projects for large-scale power infrastructure systems.
