Guest Lecture: Practical Considerations and Significance of Power System Studies

The Department of Electrical and Electronics Engineering organized a Guest Lecture on the topic ’Practical Considerations and Significance of Power System Studies‘. This lecture was organized on 26^th September, 2020, through the Microsoft Teams online platform. The event started at 2.00 pm and concluded at 4.00 pm. The 5^th and 7^th semester students and the faculty of the EEE department attended the lecture.

The lecture was delivered by Mr. P V Praveen Gautam, Senior Domain engineer, Hitachi-ABB Powergrids. His area of expertise includes power system operation and control, power system stability, dynamic and power system protection among other things. In the course of the lecture, he explained about the basics of power system, power flow and significance of power system studies.

The idea behind arranging this lecture was to enlighten the students with content beyond their syllabus, in the area of power system operation, load flow analysis and stability.

Power system study is very important for the protection of the power system. Power system study includes load flow analysis, effect of power factor on power system, short circuit study, motor starting effect, transient stability analysis, protection aspects of system, harmonics analysis etc. Ever since the 20th century, till recent times, all major power generating stations across the globe have mainly relied on AC system as the most effective and economical option for generation and transmission of electrical power.

A power system study is made up of various engineering analyses investigations. The goal of each study is to have a safe, efficient and reliable power system for your facility, under both normal and abnormal conditions. A power system comprises of the various subsystems that include generation, transmission and distribution. The goals of power system analysis are the following:

• To model or to execute per phase analysis of power system components
• To monitor the voltage at different buses, real and reactive power flow between buses
• To plan future expansion of the current system
• To analyze the system under different fault conditions, based on different scenarios
• To design the Protective Devices, as well as to investigate the ability of the system to handle small and large disturbances or faults of any kind.

OUTCOME OF THE GUEST LECTURE:

The students were able to enhance their knowledge about power system and its significance. Students gained knowledge on power system load flow analysis, power system stability analysis, short circuit analysis and relay coordination.
