Alpha-elsec Defence & Aerospace Systems Senior Engineer Interview Questions and Answers

DCA and PLC are commonly used acronyms in the field of engineering.

• DCA stands for Direct Current Amplifier, which is a device used to amplify direct current signals.

• PLC stands for Programmable Logic Controller, which is a digital computer used for automation of electromechanical processes.

• DCA and PLC are essential components in various engineering applications such as industrial automation and control systems.

Equipment used in steam turbine include turbine blades, nozzles, casing, rotor, bearings, and governor.

• Turbine blades: convert steam energy into mechanical energy

• Nozzles: control the flow of steam into the turbine

• Casing: contains and directs the steam flow through the turbine

• Rotor: connected to the turbine blades and rotates to generate power

• Bearings: support the rotor and reduce friction

• Governor: regulates the speed o

The Honeywell DCS (Distributed Control System) is a modular system consisting of controllers, I/O modules, and operator stations.

• Consists of controllers, I/O modules, and operator stations

• Uses a network to communicate between components

• Allows for centralized control and monitoring of processes

• Supports various communication protocols such as Modbus, OPC, etc.

• Example: Honeywell Experion PKS

PID stands for Proportional-Integral-Derivative, a control loop feedback mechanism used in engineering.

• PID is a control algorithm that calculates an error value as the difference between a desired setpoint and a measured process variable.

• Proportional (P) control responds to the current error value.

• Integral (I) control accumulates past errors to correct the present error.

• Derivative (D) control predicts future errors bas...read more

To assign a new channel in Honeywell DCS, you need to access the configuration software and follow the steps to add the channel.

• Access the Honeywell DCS configuration software

• Navigate to the channel configuration section

• Add a new channel by specifying the channel number, type, and other relevant parameters

• Save the changes and verify the new channel is successfully assigned

Interlocks and permissives are safety mechanisms in place to prevent unsafe operation of boiler and turbine systems.

• Interlocks prevent certain actions from taking place unless specific conditions are met

• Permissives allow certain actions to take place only if specific conditions are met

• Example of interlock: Boiler feed pump interlock prevents the boiler from starting unless the feed pump is running

• Example of permissive:...read more
