pec-pve

 Solar PV Emulator 

PEC-PVE emulates the electrical behavior of the silicon solar panel under various conditions, installation locations, and gives the freedom to perform experimentation not possible in cloudy weather. This instrument has four independent emulated panels, which can be used independently, connected in series or parallel. In addition, the PEC-PVE series can emulate the Shading phenomena of PVs.

PEC-PVE also characterizes the I-V curve of an independent solar cell which can be used with emulated panels or with real solar panels to obtain current and power characteristics as a function of voltage [P(I)/V(I )] photovoltaic sources with currents up to 10.0 amperes

Features

• Open circuit voltage of the panel: 21V
• Panel short-circuit current 1 A
• 7” color touch screen
• Irradiance and temperature of each panel is independently adjustable (0-1000) W/m².
• Graphic presentation I (V), P (V) and power point.
• 220V power supply
• 4mm banana output

pec-wte

Wind Turbine Emulator 

PEC-WTE is a real-time wind turbine emulator to study the static and dynamic characteristics of the wind turbine by simulating its behavior using a powerful asynchronous motor.
The PEC-WTE can emulate a measured or real-time wind profile (wireless sensor), a constant profile, a linearly varying profile and random variations.

Features

  • Motor type: asynchronous.

  • Motor power: 1.1kw

  • Speed: 1500 rpm

  • HMI: 8" touch screen

  • Multiple wind speed profiles (programmable constant, pre-programmed variable, real-time measurement).

  • Power supply: AC 220V.

  • Size: 480x177x300mm

em-dfig

Doubly Fed Induction Generator  

EM-DFIG is typically used in applications that require varying speed of the machine's shaft in a limited range around the synchronous speed, for example ± 30%, because the power rating of the frequency converter is reduced similarly (variable speed wind turbine concept.). The stator windings of the three phase machine are brought out to 4mm terminals on the housing for either or connection. The rotor windings are also accessible from the housing terminals.

Features

  • Power 1.5 kW/4 kW.
  • Stator voltage: 220V delta / 380V star.
  • 3A/9A stator current.
  • Speed ​​1500Rpm/3000Rpm.
  • Protection thermostat

Weather Station   

The automatic weather station is used for measurements of atmospheric temperature and humidity, as well as pressure, wind speed and direction, solar radiation, luminosity, precipitation, soil temperature and humidity and CO2. The station consists of different types of sensors, LCD display, weather data collectors, chassis, bracket and other parts. It can be widely used in meteorology, hydrology, agriculture, forestry, scientific research and other fields.
