Technical specification for solar energy resource
real-time monitoring of photovoltaic power station
1 Scope
This standard specifies the technical specification for site selection, data
measurement, installation of measuring equipment, instrument calibration and
maintenance, measurement data collection and transmission, and measurement
data storage and arrangement for solar energy resource real-time monitoring of
photovoltaic power station.
This standard applies to photovoltaic power station.
2 Normative references

Measurement of sunshine
3Terms and definitions
The following terms and definitions apply to this standard
3.1
Photovoltaic (PV) power station
The generating system that uses the photovoltaic effect of photovoltaic cell and
directly converts solar radiation energy into electrical energy. Generally it includes
transformers, inverters and PV array, as well as related auxiliary facilities, etc.
3.2
Direct normal irradiance
Irradiance on a plane that direct solar radiation is perpendicular to the beam.
3.10
Diffuse irradiance, scattering irradiance
In addition to the contribution of direct irradiance, it is the radiant flux irradiating to
unit area from sky.
3.11
Global solar irradiance
It is the total solar radiation flux of incidence on the horizontal surface of unit area,
also known as total radiant emmittance.
3.12
Sunshine duration
It is the sum of time interval that direct solar radiation irradiance is greater than or
equal to 120W/m2, also known as sunshine duration.
3.13
Duration of possible sunshine
Without any shadowing conditions, when the center of the sun enters from eastern
horizon into western horizon in the place, it is the time of light reaching the ground.
4 Site selection of test-station
4.1 Meteorological monitoring equipment shall be built within photovoltaic power
station, because it is easy for observers to observe.
4.2 In meteorological information collection system, there shall be no obstruction for
the above plane of sensing element of environmental information observing
instrument; if not satisfied, the altitude-difference should be maintained by more than
10 times-distance from the obstacles, so as to reduce the impact of surrounding
environment on equipments.
5 Data measurement
5.1 Total irradiance
c) Measurement accuracy. less than 5%.
d) Working environment temperature. -40 °C ~ + 60 °C.
5.4 Sunshine duration
Use heliograph to observe. Sunshine recorder accumulates automatically the
sunshine duration of the day, the unit is h. Observations of heliograph shall meet the
requirements of QX/T 56. The technical parameters required are as follows.
a) Measuring range. 0 ~ 24h;
b) Measurement accuracy. less than ± 0.1h;
c) Resolution rate. 0.1h;
d) Working environment temperature. -40 °C ~ + 60 °C.
5.5 Wind speed
Use wind speed sensor to observe. The wind speed sensor samples once per
second, and automatically calculates and records the arithmetic mean wind speed
every 5 minutes, the unit is m/s. The technical parameters of wind speed sensor are
as follows.
a) Measuring range. 0m/s ~ 60m/s;
b) Measurement accuracy. ± 0.5m/s (3m/s ~ 30m/s).
c) Working environment temperature. -40 °C ~ + 60 °C.
5.6 Wind direction
Use wind direction sensor to observe. Wind direction and wind speed are
synchronous acquisition. Automatically calculate and record vector average wind
direction every 5min, the unit is (°). The technical parameters of wind direction
sensor are as follows.
a) Measuring range. 0 ~ 360 °;
b) Measurement accuracy. ± 5 °;
c) Working environment temperature. -40 °C ~ + 60 °C.
5.7 Environment temperature
Use thermometer to observe. The thermometer samples once every 10s, and
collects 6 samples every minute. Delete 1 maximum and 1 minimum; the arithmetic
average of the remaining four samples is the instantaneous value of the minute.
d) Check whether the shading of scattered radiation meter completely shade the
sensing surface and the glass cover of instruments, or adjust immediately.
8 Acquisition and transmission of measurement data
8.1 Use data acquisition device to gather data. The technical parameters
requirements of data acquisition device are as follows.
a) Have the functions of collecting, calculating and recording all measuring
elements of this specification;
b) Have the functions of remote data transmission and remote configuration and
maintenance;
c) Be able to fully save the amount of data collected at least 1 month;
d) Have the function of regularly automatic timing;
e) Have the functions of network failure data caching and data self-recovery;
f) Have the function of fault alarm.
8.2 Measurement data transmission shall use wireless or wired transmission, the
normal operation rate of transmission data shall be no less than 95%.
8.3 Measurement data transmission interval shall not exceed 5min, and time delay
shall be less than 1min.
8.4 Data format
The specific data format of recorded and transmitted measurements is described in
Table 1.
