Mid-Term Progress Report ECE 412 February, 2013 Variable Speed Drivers for sewage lift station Motor Tasks Completed Till date: Motor Selection...

I have attached two files. One is the proposal and the other is the midterm progress report that has to be done. For the report simulation of the motors has to be done in either Psim or SimuLink. So, the only thing that has to be done is the simulation part. I have never done simulation so could you help me out with this? Thanks....
Mid-Term Progress Report ECE 412 February, 2013 Variable Speed Drivers for sewage lift station Motor Tasks Completed Till date: 1. Motor Selection Depending on the requirement. 2. A comprehensive design, analyses, and simulations of all the components of the proposed Sewage Lift Motor have been performed on Simulink and PSIM. 3. Typical Load and electricity consumption data will be collected from the nearest sewage treatment plant. Tasks Ahead: 1. All the steady state and transient analysis of the system will be performed for different input condition and on different load and failure conditions. 2. The energy efficiency and economic prospective of VSD for sewage plant will be presented to show the importance of the VSDs. 3. All the simulation Results will be plotted and will be shown in appropriate manner to critically compare the performance. Description of the tasks accomplished: 1. Data Collection: We visited "Stickney Water Reclamation Plant" situated in Chicago for the data collection of load and motor specifications. The Information we got is given below: "The MWRD is the largest wastewater treatment plant in the world, the Stickney Water Reclamation Plant in Cicero, Illinois, in addition to six other plants and 23 pumping stations. The District treats an average 1.5 billion US gallons (5,700,000 m 3 ) of wastewater each day. It also shares responsibility with the Army Corps of Engineers for the Chicago Area Water System (CAWS), including the Chicago Sanitary and Ship Canal and approximately 76 miles (122 km) of waterways, part of a national system connecting the Atlantic Ocean, Great Lakes, and the Gulf of Mexico" 2. Motor Selection The pump and motor units shall be the submersible type to deliver the design flow through minimum 4” discharge force mains. The pumps shall be capable of passing spheres of at least 3” in diameter and shall be driven by 3 phase, 460 volt, 60 Hz. motors. The units shall be as manufactured by Flygt, Fairbanks Morse, ABS or approved equal. No grinder pumps will be allowed. The discharge connection elbows shall be permanently installed in the wet well and the pumps shall be automatically connected to the discharge connection when lowered into place and shall be easily removed for inspection or service by means of stainless steel lifting chains. There shall be no need for personnel to enter the wet well. Major pump components shall be gray cast iron, Class 30, with smooth surfaces devoid of blowholes or other irregularities. Thermal sensors shall be used to monitor stator temperatures and specialized relays/sensors shall be supplied to the control panel manufacturer prior to panel construction. Impellors shall be of gray cast iron, Class 30, dynamically balanced, single or double shrouded non clogging design, with stainless steels shafts, and be capable of handling solids, fibrous materials, heavy sludge and be capable of passing a sold 3” diameter sphere.

Mid-Term Progress Report ECE 412 February, 2013 3. Rectifier design on PSIM We have completed the design of Bridge Rectifier and different steady state simulation has been performed in PSIM. Filter is designed to remove the ripple to minimum acceptable level of less than 1%. This works for 3-pahse input Isolation has been checked at the input of the Rectifier by putting a transformer at the Input. 4. Inverter Design Inverter is also simulated for AC to DC conversion and different graphs are plotted. 5. Control logic Implementation: This is basically the control logic block which will control the DC current supplied to the sewage lift motor. 6. Electrical and control panel Requirements and function to be implemented finalized. We have given control for running the motor in two different mode namely: Normal Mode Variable Speed Mode. Also there will be control to switch off the Motor, Indicator for water level detection. Alarm Signal if it overflows and there will be provision for a secondary motor system in case of heavy load.

Abstract for Major Design Project ECE 412 February, 2013 Variable Speed Drivers for sewage lift station Motor The Major Design Project will consist of the design and analysis of Variable Speed Drives for sewage lift station motor. Sewage lift station operates in different load condition and to run the motor at same speed results in loss of energy and therefore VSDs for sewage system is proposed and will be critically analysed with respect to fixed speed motor. A circuit Model of Drive for sewage lift station motor will be developed and simulation will be performed for different cases and performance will be evaluated and discussed. A typical block diagram of sewage lift station system operated with VSDs and fixed speed control is shown in the Figure1.1 below: 3-Phase Input Speed Control Signal Ref Signal Figure .1: Block Diagram of Typical VSD System First part of the project will be about designing (or modelling) of Different component of the system on Simulink (MATLAB) or PSIM and extensive parametric analysis will be performed. Second phase of the project deals with the performance analysis of the developed VSD for the system and will be compared with the fixed speed control. Different performance measures will be evaluated using and final conclusion will be presented as the energy savings and price overload for the system. A comprehensive design, analyses, and simulations of all the components of the proposed Sewage Lift Motor on Simulink and PSIM. Typical Load and electricity consumption data will be collected from the nearest sewage treatment plant. All the steady state and transient analysis of the system will be performed for different input condition and on different load and failure conditions. The energy efficiency and economic prospective of VSD for sewage plant will be presented to show the importance of the VSDs. All the simulation Results will be plotted and will be shown in appropriate manner to critically compare the performance. 1
