Course Overview

This course shall explore different and unique types of dynamic and static Uninterruptible Power Supply (UPS). Electrical power outages are pernicious to electrical devices as well as power networks and systems. Therefore, UPSs are needed to ensure the electrical power supplied is stable, reliable, and secure. In addition, UPS improves power quality for semiconductor utilising devices.

What is UPS and its types?

Some types of UPSs are already making waves in the market because of their security and stability, such as the dynamic uninterruptible power supply or the infamous diesel rotary uninterruptible power supply (DRUPS) systems. They provide a reliable and clean alternating current which is much needed by consumers everywhere, such as in powering important devices or powering data centres. The two superior and infamous UPSs do not use batteries and are therefore more reliable and greener.

UPSs are vital in power supply stabilisation and a must-have device for this century. The main advantage of UPS is that they have components such as batteries, inverters, rectifiers, and in the recent past, new technologies that use power electronics components.

How does uninterruptible power supply work?

UPS is expected to provide the system with maximum possible reliability and improved quality while maintaining the costs low. More often, achieving such requirements becomes a major design and maintenance challenge and dilemma between improvements and the costs of improving UPSs. A compromise between the power quality and reliability is made from one side and the investment from another end. Due to these reasons, power loads are classified according to the effects that will arise if their power supply is interrupted.

Critical, non-essential, and essential is the classification used to categorise loads. Non-essential loads have a minor effect when their power is interrupted. There is a significant effect on essential loads, especially if the interruption takes a duration above a set threshold value. Critical loads should never be interrupted as the impact is huge with hazards and costly results.

This Zoe course shall handle the following:

• The modern technologies used in UPS

• Importance of having an efficient UPS

• Battery monitoring and electrical power quality

• Types of batteries, their maintainability, and types

• Operations and construction of UPS

Course Objectives

This course intends to teach participants the main difference between static and dynamic UPS and battery maintainability. Participants are expected to have understood the following concepts after learning:

• To appreciate the importance of battery monitoring in UPS

• Why power quality is important in UPS

• Analyse characteristics of UPS batteries

• Understand and thoroughly master the operations of different static UPS

• Deeply understand UPS topologies

• Comprehensively understand the importance of continuous power supply for critical and essential loads

Training Methodology

Training for this course shall be administered by well-trained professionals who are reputable in their various and respective fields. There will be theoretical sessions and practicals both in class and online. All the participants shall be assigned tasks and assignments in groups and as individuals. However, everyone is highly encouraged to interact with the tutors and other participants. Role-play is part of this course teaching methodology whenever it can be used.

Questions are also encouraged to help learners understand the concepts thoroughly.
