Design Checklist-Instrumentation & Control Systems (typical / guideline)
Design Checklist-Instrumentation & Control Systems (typical / guideline)Stephanus Roux C Eng , IntPE(uk) , FIET
This document provides design criteria and a checklist for instrumentation documentation. It outlines requirements for various documentation deliverables including instrument indexes, loop diagrams, specifications, calculations, installation details, location drawings, purchase documents, software and hardware documentation, and vendor documentation. It also provides guidance on general instrumentation including required control systems, signal levels and indications, tagging, and electrical classifications. The overall purpose is to ensure consistent and complete documentation is developed to support construction, startup, and long-term maintenance of the facility's instrumentation and control systems.Practical Distributed Control Systems (DCS) for Engineers and Technicians
This workshop will cover the practical applications of the modern Distributed Control System (DCS). Whilst all control systems are distributed to a certain extent today and there is a definite merging of the concepts of a DCS, Programmable Logic Controller (PLC) and SCADA and despite the rapid growth in the use of PLC’s and SCADA systems, some of the advantages of a DCS can still be said to be Integrity and Engineering time.
Abnormal Situation Management and Intelligent Alarm Management is a very important DCS issue that provides significant advantages over PLC and SCADA systems.
Few DCSs do justice to the process in terms of controlling for superior performance – most of them merely do the basics and leave the rest to the operators. Operators tend to operate within their comfort zone; they don’t drive the process “like Vettel drives his Renault”. If more than one adverse condition developed at the same time and the system is too basic to act protectively, the operator would probably not be able to react adequately and risk a major deviation.
Not only is the process control functionality normally underdeveloped but on-line process and control system performance evaluation is rarely seen and alarm management is often badly done. Operators consequently have little feedback on their own performance and exceptional adverse conditions are often not handled as well as they should be. This workshop gives suggestions on dealing with these issues.
The losses in process performance due to the inadequately developed control functionality and the operator’s utilisation of the system are invisible in the conventional plant and process performance evaluation and reporting system; that is why it is so hard to make the case for eliminating these losses. Accounting for the invisible losses due to inferior control is not a simple matter, technically and managerially; so it is rarely attempted. A few suggestions are given in dealing with this.
Why are DCS generally so underutilised? Often because the vendor minimises the applications software development costs to be sure of winning the job, or because he does not know enough about the process or if it is a green-field situation, enough could not be known at commissioning time but no allowance was made to add the missing functionality during the ramp-up phase. Often the client does not have the technical skills in-house to realise the desired functionality is missing or to adequately specify the desired functionality.
This workshop examines all these issues and gives suggestions in dealing with them and whilst not being by any means exhaustive provides an excellent starting point for you in working with a DCS.

Control valve positioners
A positioner is a feedback controller device that ensures a control valve is in the correct position according to a control signal. It senses the valve's position and compares it to the signal from an I/P converter. Based on the difference or "error", it positions the valve to reduce the error to zero. Positioners improve the accuracy of a valve's response by reducing issues like friction, dynamic forces, and non-linearities. Modern digital positioners no longer require an I/P converter and offer additional features like diagnostics and partial stroke testing.
Control Valve and Types of caged trims
Valves are the components in a fluid flow or pressure system that regulate

Inspection, Testing and Commissioning of Electrical Switchboards, Circuit Bre...
THE WORKSHOP:
Whether you are designing, specifying, installing, testing or commissioning electrical equipment from small to large commercial and industrial installations, you need to have a thorough understanding of switchboards, switchgear, circuit breakers and associated protective relays.
The overall focus of this workshop is on electrical inspection, testing and commissioning and will commence with a detailed examination of switchgear (and circuit breakers). Circuit breakers are critical components in electrical distribution systems and their operation significantly affects the overall operation of the system. Protection relays are then discussed. These are used in power systems to maximise continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilisation of power in plant, industrial and commercial equipment.
We cover commissioning and periodic inspection of cables and their various failure modes and how to detect these faults. The often neglected topic of switchboards will be detailed next, followed by the interesting topic of interfacing to the control system (either PLC’s or other control devices).
Case studies and practical sessions are used throughout to illustrate key practical principles.
This workshop covers key elements in a practical and project focused way. Many people assume (wrongly) that inspecting, testing and commissioning is a fairly straightforward process and is simply a rubber stamp confirmation of a so-called outstanding design. Our experience in the field demonstrates quite the opposite; where the litany of problems ranges from design and installation errors to equipment manufacturing defects. It is best that these problems are identified and corrected before the inevitable downtime comes in an operational installation where many thousands of dollars are lost in correcting the faults. The situation today is made more challenging by the heightened safety requirements and interfacing to low powered electronic control and monitoring devices (such as PLC’s) using software that has to also be verified.

protection and relay scheme
Protective relays are used to isolate faults in electrical systems and protect equipment from damage. There are different types of relays including electromagnetic, solid-state, and microprocessor-based relays. Relays are used for motor protection including overload protection, locked rotor protection, and single phase/unbalance protection. Transformer protection includes gas and temperature monitoring as well as differential and ground fault protection. Generator protection includes differential, ground fault, and negative sequence protection to prevent phase unbalancing.
Relay and switchgear protection
Relays sense abnormal voltage and current conditions and send signals to circuit breakers to isolate faulty parts of a power system. Electromagnetic induction relays use eddy currents produced in a disc to generate torque. There are different types of overcurrent and directional relays. Distance relays use impedance, reactance, or mho principles. Transformer and feeder protection uses overcurrent, distance, or pilot wire schemes. Circuit breakers use oil, air, sulfur hexafluoride, or vacuum to extinguish arcs and open faulty circuits. Instrument transformers reduce high voltages and currents to safer, measurable levels for meters and relays.
