Alternative/Renewable Energy Training Programs

Lab-Volts Alternative Energy Training Program wasdeveloped as a three-tiered program. It begins at thesecondary education level with 40 hours of GraymarksGREENtech program and continues with hands-ontraining on our comprehensive training systems: So-lar/Wind Energy, Solar Thermal Energy, Wind TurbineNacelle, Electric Pitch Hub, Hydraulic Pitch Hub, Geo-thermal, and Grid Tie.

These secondary education programs focus on in-stallation and operation, including electrical skills,maintenance and support, and an understanding ofthe set-up and use of stand-alone (a small renewableenergy system that is not connected to the electricitygrid) and grid-tied (a small renewable energy systemthat is connected to the electricity grid) renewableenergy systems.

The college and university two-year program is basedon Lab-Volts Electromechanical Systems trainer andfocuses on power generation, transmission, anddistribution and voltage/frequency power synchroni-zation, as well as control of the many different typesof generators used in wind and hydro power. Alsoincluded in this program are the power electronicsbehind alternative and renewable energy systems,battery chargers and small electric vehicles, hydrogenfuel cells, and energy storage.

Lab-Volt also offers comprehensive simulation trainingwith our Wind Farm Simulator and Grid-Tie Systemssimulation software.

to standing strapped to the top of the nacelle, over-looking the countryside. Each sector contains turbineicon call-outs that are accessed as needed for in-depthconcepts related to wind-power-specific technologies.

A Wind Farm is a set of Wind Turbines, located near each other, sharing a common point of connec-tion to the electrical distribution grid called a Common Connection Point. Generally, a Wind Farm has aSCADA (Supervisory Control and Data Acquisition) system used to control individual wind turbines and

monitor the entire wind farm. The Wind Farm Simulation Software is a software-only solution: no specialhardware is required, only a PC with adequateperformance capabilities. The HMI (Human Ma-chine Interface) is designed to be user-friendlyand intuitive. It presents every parameter as wellas the values of the signals, both internal to thewind turbine and published to the SCADA sys-tem.
