1 Introduction
Following an order of Ecoenergo S.A. a one year wind measurement campaign has been performed
at a site near the village of Olăneşti, Moldova. The DEWI station number is Station.426.
The DEWI working title of the station is “Station.426, Olăneşti”.
The aim of the measurement is to study the wind and meteorological conditions at the site in order
to compile a database that can be used for wind energy yield assessment for a wind farm. The
measurement of the wind is performed at several heights with a maximum height of 101.0 m. The
wind direction has been measured at two heights, air temperature and relative humidity
measurement have been performed at one height.
The norms and guidelines [1] and [2] have been considered in the layout of the system setup.
Anemometer calibration has been performed according to [3], by DEWI a full member of MEASNET.
The wind measurement is performed with anemometers of the type First Class Advanced.
DEWI is responsible for the installation of the instruments on the mast. The data acquisition system
and transfer system are provided by DEWI. The mast is provided by EGERES company from Izmir in
Turkey.
This report is based on the data of the following measuring period:
Period of measurements: 01.07.2011 (00:00) to 30.06.2012 (23:50) (CET).
It is ensured that the results presented in this report have been measured in an unbiased manner,
following the latest methodological developments and to the best knowledge of the participating

4 Data Acquisition and Data Processing
4.1 General Description of the Measurement System
4.1.1 Meteorological Mast
A lattice was used for the meteorological mast. This mast has been provided by EGERES company
from Izmir, Turkey. The tower height is 100.0 m. It has been erected at an altitude of about 145 m
above sea level.
The mast layout has been designed to meet the requirements of IEC 61400-12-1 [1].
The installation of the mast and all sensors has been performed by DEWI (for details please see Tab.
4.1).
On 27.12.2011 the top anemometer v1 had to replaced due to malfunction. This replacement has
been performed by DEWI staff and a mast fitter team. The mast configuration was not influenced
significantly by these exchanges.
The orientation of the booms was checked by DEWI with both compass and GPS during the
installation and have been verified.
A flashlight of type “Carmanah M601” has been mounted at a height of 95.0 m. It is electrically
independent of the measurement system.
The following sketch gives the major dimensions of the tower, as well as the booms and mountings
(please see 9.4 for more details).

4.1.2 Wind Speed
The measurement of wind speed was performed at several heights. Five anemometers have been
installed.
At the top of the tower, at 101.0 m, a cup anemometer of the type Thies First Class Advanced has
been mounted on a single top boom (Fig. 4.1). The anemometer is classified following IEC 61400-12-
1, Annex I [1] as a class 3.0 B sensor [2].Due to malfunction starting 28.10.2011, the top anemometer
had to be replaced (for details see Tab. 4.1).
A second anemometer (v2) of the same type (Thies First Class Advanced) was mounted in 99.0 m (Fig.
4.1.).
Three more anemometers of type Thies First Class Advanced have been mounted on single booms in
78.0 m (v3), 61.5 m (v4) and 40.3 m (v5) height above ground (see Fig. 4.1).
The anemometer v5 has been connected since 18.07.2011 (17:00 h), (please see 4.1.5 for details).
For mounting details please see Fig. 4.1 and 9.4.
All anemometers have been calibrated by DEWI GmbH in the wind tunnel (MEASNET [4], DAkkS/DKD
accreditation) before the wind measurement period. The respective calibration certificates are given
in the appendices (see section9.1).
Through an in-situ comparison of the anemometers the measurement was controlled continuously
(see section 6.3).

4.1.3 Wind Direction
The main wind direction was measured at a height of 98.9 m on the met mast with a wind vane of
type Thies First Class (see Fig. 4.1). The boom points towards 112 degrees, the North marker of the
wind vane points towards the tower.
A second wind vane of the same type has been mounted on a boom at a height of 61.3 m. The boom
points towards 112 degrees, the North marker of the wind vane points towards the tower.
The vanes use a ratio metric measurement principle.
Mounting details are given in Fig. 4.1 and 9.4.
The magnetic declination at the site has been considered (see section 2.1). All directions are given
with respect to True North.
The accuracy of the sensors is 1 degrees. The accuracy from the alignment of the wind vanes on the
boom is considered to be 3 degrees.
The function of the wind vanes have been checked by DEWI (see 9.2).

4.1.5 Data Acquisition System
The Control Cabinet has been placed 3.7 m above ground. The data acquisition system was provided
by DEWI.
During the initial installation, a logger of type Ammonit METEO 32 has been installed. It has been
replaced on 18.07.2011 by a logger of type Ammonit METEO 32x, which actually had been planned
from beginning on. The model Ammonit 32x offers more measurement channels, which are
necessary to connect the 5th anemometer.
From 18.07.2011 on the measured data were recorded by a data logger of type Ammonit METEO-32x
with a sampling rate of 1 Hz. The internal software had the firmware V 1.9. The logger has several
different ways of connecting to signals. These can be pulses, analogue signals or a readily digitized
data stream. The wind speed (pulses) were recorded directly by pulse counting input channels of the
logger. The logger provides also dedicated input channels for air temperature and relative humidity
as analogue channels. Wind direction is measured using a ratiometric four-wire principle.
Both data loggers have been calibrated in a climate chamber test (see 0). All channels were checked
by means of a DKD/ DAkkS-calibrated reference source. The measured values are averaged
(10 minutes) by the logger and are stored.
All input channels have been directly fed into the data logger. An additional overvoltage protection is
not in place.
The system has been powered by a 20 Watt ET-M53620 solar panel charging a battery.
The availability of the measuring system (logger uptime) during the presented power curve
measuring campaign was 99.9 %.

4.2 Data transfer
The system features a Siemsens TC63 modem. Signal strength of the modem is Q6. The access to the
logger has been protected by an individual password which knowledge was restricted to the DEWI
team.
The serial number is 355633001040049. The network operator is “Orange Moldova” The SMS phone
number is +37369261637.
The measured data were transmitted to a DEWI headquarters daily (via GSM modem) and there they
were checked and stored on a weekly basis. Various attempts have been made to operate the data
sending by Email in combination with the operator Orange Moldovia, but it appeared that at some
part of the transmission chain out of the control of DEWI this transmission had been blocked as the
system at the site reported that data had been send out.
The GSM dial in download connection furthermore provides automated modes to ensure that the
configuration of the system can be tracked to the status of every connection.

4.3 Data processing
The logger is configured to save data in units of 1/10 Hz for wind speed, and mV for analogue
channels. The direction is stored as an integer value between 0 and 360 degrees. Offsets to True
North have been set in the data logger. The error code for wind direction data is “777”.
DEWI has performed monthly intermediate evaluations of the data and issued a report for each
month of the measurement campaign.
The software used in an in-house development, Alda in version 1.4.0.1. It converts the recorded data
into correct physical quantities, calculates statistics and provides graphics to visualize the data.
Further tools written in the pattern scanning languages perl and awk have been used for assessing
specific issues.
Data has been visualized using Alda and Gnuplot 4.4, xfig 3.2.5b.
