The Relationship

Energy conservation is beneficial not only to reduce consumption and the cost of energy consumption, but also to give a better impact on the environment. In this study a simulation model is created which is a reflection of the relationship con-dition between variable frequency drive (VFD), induction motor and centrifugal pump. By creating a simulation model will be able to know the potential savings that will be provided if the variable frequency drive is used.

This paper presents optimizing the control and automation of variable torque on 3-phase induction motor using programmable neuro logic controller (PNLC) and variable frequency drive (VFD). The system was designed by developing a transfer model of the nonlinear input current from the load cells and feed to an improved PLC model for an approximate current function which is identified by the VFD with respect to the controlled load torque to power the 4.07KW rated 3-phase induction motor. The models were implemented using control system toolbox, neural network toolbox and simulated with Simulink in MATLAB. From the simulation of the improved controller model, the step response time performance of the PLC was improved from 2.25s to 1.22s with the PNLC.The simulation result of the VFD controlled 3-PIM motor shows that 37.07% of energy (power) was conserved compared to a characterized system with 20% energy conservation rate. Keywords: 4.07KW 3-phase induction motor, PLC, ANN, VFD, Energy conservation rate

Viscosity is one of the factors affecting the performance of the centrifugal pump. A centrifugal pump is a device that used driven motor called impeller to move fluid by rotational energy. This thesis is about the analysis of the performance of the centrifugal pump when transferring viscous liquids. For this project, the objective is to design and fabricate a device that can pump liquid with various viscosity using centrifugal pump. The liquids used in the experiment are comprised of a mixture of detergent and water with different ratio to alter the viscosity. The viscosity is being identified by the usage of Zahn Cup Method with the temperature kept constant at 26 °C throughout the experiment. The performance of the centrifugal pump is being investigated by four parameters which is the flowrate, Total Dynamic Head (TDH), power and efficiency. The performance of the centrifugal pump can be accessed by altering the pump shaft speed in order to get various reading for the flow rate. In order to alter the pump shaft speed, the usage of motor with Variable Frequency Drive (VFD) is implemented. The values for the flowrate and pump shaft power are measured by flowmeter and Variable Frequency Drive (VFD). The Total Dynamic Head (TDH), hydraulic power and pump efficiency is calculated based on the reading of the flowmeter and pump shaft power displayed at Variable Frequency Drive (VFD). At the end of this project, the pump performance while pumping different viscous liquids at different flowrates is being identified.

The Cost

The demand for energy is increasing rapidly and, after a few years, it may surpass the available energy, which may lead the energy providers to increase the cost of energy consumption to compensate the cost for the production. This paper provides design and implementation details of a prototype big data application developed to help large buildings to automatically manage their energy consumption by setting energy consumption targets, collecting periodic energy consumption data, storing the data streams, displaying the energy consumption graphically in real-time, analyzing the consumption patterns, and generating energy consumption graphs and reports. The application is connected to Mongo NoSQL backend database to handle the large and continuously changing data. This big data energy consumption management system is expected to help the users in managing energy consumption by analyzing the patterns to see if it is within or above the desired consumption targets and displaying the data graphically.

Metal sorting conveyor is a device that is used to separate metal and non-metal objects, the drive of this conveyor uses ½ Horse Power (HP) induction motor as its prime mover. To adjust the rotation of the induction motor 1 HP Variable Frequency Drive (VFD) is used. This VFD is set with the double speed parameter so that later the motor can rotate variably in two speeds. The input parameters of the VFD itself use switches in the form of photo electric and inductive proximity which are controlled automatically using Programmable Logic Control (PLC). The digital output of the PLC will then communicate with the digital input of the VFD so that when the object on the conveyor is detected by a photoelectric, the VFD will adjust the frequency by 8,5 Hz, if the object on the conveyor is detected by metal by inductive proximity, the VFD will set the frequency by 14,5Hz . So that at each of these frequencies the motor can rotate with speeds of 241,5 rpm and 359,5 rpm. The results of the trials carried out show that VFD can regulate in a number of speeds in a variable manner, but in this study limited to using two speeds or double speed as a variable speed experiment.
