Instruments and Equipments

Instruments and Equipments:

Data loggers:

The data logger is used to process the electrical signals received from different sensors for pre-defined time periods and record them as time series for retrieval at a later time.

The types of data loggers used at Wind Department are:

Masts:

The function of the mast is to carry and fix the sensors to the desired height. Wind Department has two different types of masts: tubular & Lattice (see pictures) with different heights ranging from 10 m up to 60 m .

Sensors:

Depending on the type of sensor, it converts wind speed, wind direction, temperature and/or solar radiation to electrical signals. Wind Department uses the following types of sensors in the measuring systems:

- Wind Speed Sensors (Anemometers):

Young 05103-5
NRG #40C
Vector A 100 LM
Thies Clima 1st Class

-Wind Direction Sensors (Wind vanes):

Young 05103-5
NRG 200P
Thies Compact

-Temperature sensors:

(PT100)

-Relative Humidity sensors:

One type of this sensor (Galtec Mela) is used

-Solar Radiation sensors (Pyranometer):

Kipp and Zonen CM 6b

Softwares:

The softwares used for data retrieval and pre-evaluation are related to the data loggers used in the measuring systems such as:

-NRG (Symphonie Data Retrieval)
-Modas
-Ammonit

Some softwares were developed at NERC by the IT Department such as:

-Organizing 1
-Organizing 2

In addition to:

-WASP8

Power Electronic Laboratory:

NERC possesses a power electronic laboratory which is equipped with the latest instrumentation and data evaluation systems that are capable of simulating the performance of PV systems 50 W-10 KW peak and wind energy systems up to 20 KW and performing the required tests in a very short period of time.
