A Brief Study about Simulation of Frequency Matching in a TANGEDCO Grid

Abstract

This work aims to provide a solution to analyze and overcome the problem of frequency deviation problem using frequency matching. This paper discusses the real case study. The various loads are analyzed in Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO) is recorded for various types of loads. MATLAB 2009B is used to conduct the power flow study using Fast Decoupled Load Flow (FDLF) method. In order to visualize the grid disturbance and frequency deviational Visual C++ is used in this paper. Voltage and Frequency regulation are the most important factors in the power quality issue. To achieve this goal in the power system and frequency is the first prerequisite. In India, load management had received more attention only after the formation of Power Grid Corporation of India Limited (PGCIL) which has been constituted to monitor the system operation and to operate the system frequency at a desired level of 50 HZ since there has been rapid growth in the Industrial, Commercial, Agricultural and Domestic sectors in the recent years and power had not left in phase with this growth. The operating range of 49.5 HZ to 50.5 HZ is designed as per the Indian Electricity Grid code (IEGC) approved by Central Electricity Authority (CEA), Govt of India. Available transfer capability (ATC) approach has been proposed for the Tamil Nadu power grid to find the power line carrying capacity of the Transmission lines.
