Electrical System Design and Basic Control with Simulink

Electrical System Design and Basic Control with Simulink IEEE student board – IEEE PELS/IAS joint chapter Author: Elisabeth Vandeventer Challenge the future 1

Outline • Introduction to the project • Development of a simple wind turbine model • Presentation of the load and grid models • Interconnection of the network elements • Implementation of secondary source and storage • Assignment Challenge the future 2

Introduction to the project • Challenge the future 3

Simple wind turbine model • http: //www. icrepq. com/icrepq 07/361 -gonzalez. pdf Challenge the future 4

Load model • Dynamic three-phase load • Input: PQ • Connect to the three phase grid Challenge the future 5

Infinite grid representation • Three phase, 230 Vrms line-to-line • Ideal representation: Challenge the future 6

Interconnection of the blocks • Use of an idealistic converter: use source output power as input and transforms it into 3 phase current waveforms Challenge the future 7

Power flow • Primary source uncontrollable • Infinite grid needs to provide power System is not stand-alone! • Need addition of: • Controllable secondary source: hydropower turbine • Electricity storage: battery bank Challenge the future 8

Hydropower turbine • Challenge the future 9

Battery bank • Challenge the future 10

Assignment – goal • Challenge the future 11

Assignment – input and outputs • Inputs to the model: • Load profile • Wind profile • Constant water flow • Quantities to visualize: • • • Wind power Hydro power Load consumption Battery SOC Power exchange with the grid Challenge the future 12

Assignment – control signals • Wind power uncontrollable • Hydropower turbine • Monitor: output power • Control with: valve opening • Battery: • Monitor: state of charge • Control with: power to inject/draw • Infinite grid: power exchange occurs automatically to ensure power balance (nothing to do) Challenge the future 13

Assignment – sources parameters • Warning: parameters in red might need to change GOOD LUCK! Challenge the future 14
