Aims

This module aims to provide fundamental knowledge and skills in the Electro-Mechanical Systems and Systems Safety so that students will know the physics behind the actual physical systems and related safety issues. This module enables students to be on the right footing when they chose to design a safe system comprising multiple sub-systems

Outline Of Syllabus

1. Machine theory, rotating and stationary reference frames, phase transformations.
2. Circuit analysis of electrical machines, Induction machines.
3. Transient behaviour of machines, The design of modern electrical drives, with consideration
of the machine, power electronics and control requirements.
4. Process instrumentation and Automation Lifecycle.
5. SCAI, Functional Safety, Safety Life Cycle, Safety-Critical Systems, Layers of Protection,
FMEA, Systems Thinking in Safety.

Learning Outcomes

Intended Knowledge Outcomes

At the end of the module, students should:
• Demonstrate and discuss the steady-state and transient performance of all common
machine types.
• Compare and discuss the different types of drives and their control requirements.
• Describe and explain the importance of process instrumentation in process safety and
reliability engineering.
• Know what is meant by Functional Safety, different SIL Levels, what constitutes Safety
at the component level, Safety at Systems level.
• Have knowledge of how to go about designing a Safe System of systems using FMEA/STPA and
other techniques.

Intended Skill Outcomes

At the end of the module, students should have the following:
• Ability to fully model and calculate the steady-state performance of all standard
machines types.
• Problem-solving skills to apply and analyse transient modelling of machines and generators
to solve problems.
• Determine appropriate instrumentation based on safety considerations.
• Perform SIL levels of existing design and propose how system safety can be improved.
• Design a safe system with methodologies such as FMEA/STPA.
• Evaluate and assess existing systems for their safety level.

Teaching Rationale And Relationship

The teaching is conducted via lectures and tutorial with small group discussions during class. This is complemented with self-study and preparation of tutorial solutions, quiz, coursework/project and final examination to provide feedback on student learning. Teaching materials are made available to the students online for self-study and preparation at their own pace. Tutorial questions offer the opportunity for practice in analysis and synthesis. Tutorial classes enable students to ask questions and clarify any doubts.

Due to the emerging Covid-19 situation, it is likely that some or all of the classes are conducted online. Attendance will be taken irrespective of whether the class is online or face-to-face, and students are expected to switch on their camera for online classes.

Assessment Rationale And Relationship

The written exam enables students to demonstrate understanding and apply knowledge and skills learnt to solve engineering problems. The quiz involves problem-solving and theoretical questions to assess the students’ progress and learning. Coursework assignment provides students more time to think about a more significant problem and offer engineering solutions to it and present the safety case. This also allows them to work as a team to handle larger issues on systems safety
