Electrical Doctor – Real-time Health Diagnosis for Electricity Supply System (REF:C-0033)
E&M InnoPortal Trial Project Ref. No.:

Overview

The "Electrical Doctor – Real-time Health Diagnosis for Electricity Supply System" is a collaborative project between Electrical and Mechanical Services Department (EMSD) and the City University of Hong Kong, focusing on the Low Voltage Switchboard (LVSB). LVSB is the heart of the electricity supply system, ensuring a reliable power supply to various premises. By introducing a real-time health diagnosis system for LVSB, using IoT sensors, analytic algorithms and an integrated online monitoring platform, this project visualises the overall LVSB's health condition, detailed parameters and associated information. This cutting-edge project represents a transformative step towards proactive health monitoring and maintenance strategies, aiming to ensure the reliability and efficiency of electricity supply systems to deliver uninterrupted power to premises.

Problem Addressed

The existing electricity supply systems face a challenge due to the absence of real-time monitoring and health diagnosis capabilities. This could lead to potential system failure, equipment deterioration and ineffective capacity utilisation. To tackle with the issue, there is a need for an innovative solution that enables real-time health monitoring and diagnosis of LVSB. This solution aims to identify potential faults in a timely manner, allowing proactive and effective maintenance strategies.
Innovation

The innovative system consists of several key components to revolutionise the monitoring and maintenance of LVSBs. Over 10 types of innovative IoT sensors are installed in switchboards and switchrooms for comprehensive data collection.

Alongside these advanced sensors are inventive health diagnosis algorithms. These algorithms analyse the data collected by the IoT sensors, providing insightful and predictive assessments of the LVSB's condition. By leveraging these data, the system detects potential issues, predicts maintenance needs and enhances the overall reliability of the LVSB.

Additionally, the system comes with an integrated online monitoring platform that offers real-time visualisation of the LVSB's overall health condition with five health indexes to facilitate a comprehensive understanding of the LVSB's performance. Furthermore, the platform displays detailed parameters and associated information, empowering users to make informed decisions about maintenance and operational strategies.
