Abstract

This research is purposely to study about the Lightning Detection System (LDS). In Malaysia, LDS are managed by Malaysia Meteorology Science (MMS) and Tenaga Nasional Berhad (TNB). LDS typically is based on Time of Arrival mainly locate the lightning strike point and indicating the value of current lightning (A), voltage lightning (V), distance (KM), and direction. However, real profile of each lightning event was not being exposed by the developer of the LDS because of its confidential value. The problematic issue as stated above motivate author to propose to renovate the LDS in such a way that the system allow the user to see the real profile of lightning profile from each event. In this project, the author tries to explore the lightning detection system based on the real measurements which is known as accurate-stroke-count that has been conduct by many well-known investigators by considering two main components which are zero crossing and rising time. These two parameters which are zero crossing and rising time has been used for modelling of automatic analysis program by using MATLAB R2019b via implementing the Feature Extraction Technique. The data that uploaded in the MATLAB R2019b usually in normalized raw data. But, all of these raw data has been processed by using the calculating technique known as the feature extraction method. The feature extraction method is calculating the value of automatic rising time detection and automatic zero crossing detection. In the final process of this project, the author showed all of the processed data automatically in Graphical User Interface (GUI). the value shown in GUI following the characteristic of lightning based on the parameters.
