Ecosense installs renewable energy labs at Sardar Swaran Singh NIRE, Punjab


R&D Department-III at Sardar Swaran Singh National Institute of Renewable Energy welcomes Ecosense’s Solar PV and Wind Energy Lab


Sardar Swaran Singh National Institute of Renewable Energy (SSS-NIRE), Kapurthala (Punjab) is an autonomous Institution of the Ministry of New and Renewable Energy, Government of India. The objective of the Institute is to carry out and facilitate research, design, development, testing, standardization and technology demonstration eventually leading to commercialization of R&D output.


SSS-NIRE has three R&D Laboratories. Ecosense established Solar PV and Wind Energy Lab at SSS-NIRE’s R&D Lab-III.


Ecosense installed the following equipments:
1. Solar PV Grid Tied Training System
2. Wind Energy Training System


1. Solar PV Grid Tied Training System


Solar PV Grid Tied Training System is a compact version of an actual Solar PV Grid Tied power plant. The system enables user to study wiring and interconnections of different components involved in the system to develop basic understanding of working and operation of a Grid connected system. A user can understand underlying principles power electronics, its applications in power system and challenges like harmonics and grid synchronization by doing various experiments. The system also provides scope for further research.


Solar PV Grid Connected Training system enables user to learn about Solar Grid -tied technology. Using this system, a user gains knowledge of connecting an auxiliary grid (Solar PV) to the main grid, its essential components and transfer of power between the two grids. Using this system user gains knowledge in the following areas:


1) Effect of different types of loads on Electrical Grid
2) Effect of capacitance and inductance in Transmission lines
3) Interfacing requirement of an auxiliary Grid to main grid
4) Concept of anti-islanding

Technical Advantages of Solar PV Grid Tied Training System


• Impact of transmission line inductance on voltage quality at PCC
• Power factor improvement using capacitor bank and its impact on power quality at PCC
• Grid Synchronization of Solar PV Inverter and its performance analysis
• Evaluation of Active, Reactive and apparent power flow between PV Grid and Virtual Grid
• Net Metering
• Anti-islanding protection
• Built-in MPPT grid tied inverter
• Three ways connect/ disconnect for PV panels
• IP 65 protected PV Panels
• Can work with actual grid as well as virtual grid
• If connected with actual grid, system can run continuously as an additional renewable energy source to the lab

2. Wind Energy Training System


Wind Energy Training System is a scaled down version of actual standalone Wind Turbine power plant. This system facilitates the students with working and configurable model of wind turbine. This system gives the insight about individual components and consequences of changing the operating points of any wind turbine defined in terms of wind speed and pitch angle. Students can learn concepts like I-V characteristic, cut-off, cut-in speed etc.


This system is developed such that it can work inside a closed laboratory with an artificial wind generating unit, which makes it weather proof. User can access and utilize the system capability at any time of the day without worrying about the actual climatic conditions. This system uses a big fan mounted on top of an Induction motor, the speed of which can be controlled by a Variable Frequency Drive. User can control the speed of motor which further controls the Wind speed using the Variable Frequency Drive. The variable wind speed prompts Wind Turbine to convert Wind Energy into Electrical energy and outputs three phase electrical output. The three-phase electrical output is connected with a three-phase rectifier which converts electrical output from AC to DC. The DC output is then further connected to a Charge controller and Battery. A DC load can be connected at Charge controller output. The Battery is further connected to a home inverter which provides clean useable AC electricity.


Advantages of Wind Energy Training System


• Ecosense`s Wind Energy Training System enables students to learn about Wind Turbine technologies in easy and interactive manner. A user can study and understand about the following principles of Wind Energy Generation technology
• Evaluation of efficiency of charge controller
• Evaluation of the cut-in speed of wind turbine experimentally
• Evaluation of Tip Speed ratio (TSR) at different wind speeds
• Evaluation of coefficient of performance of wind turbine
• Draw the turbine Power versus wind speed curve
• Draw the curve between TSR and coefficient of power
• Draw the power curve of turbine with respect to the rotational speed of rotor at fix wind speeds
• Demonstrate the power analysis at turbine output
• Demonstrate the power analysis at different branches of wind turbine energy system with AC load only
• Demonstrate the power analysis at different branches of wind turbine energy system with DC load only
