Renewable Energy Testing Solutions

Dewesoft Power Analyzer allows a comprehensive analysis of renewable generation units according to FGW-TR3, VDE-AR4105, BDEW standards. Highly flexible hardware and innovative software save a lot of time during the testing process.
Picture
Testing System Overview

Renewable power plants like wind, photovoltaic (PV) and CHP (Combined Heat and Power Plant) are more and more popular and the amount of already installed units is huge. For the operation at the public grid these renewable power generation units have to fulfill a couple of requirements to contribute to a stable operation of the grid.

​The standards, which define the conditions for operating the plant at the grid, vary from country to country: e.g FGW-TR3, VDE-AR4105, BDEW etc. These regulations define the control of the active an reactive power, the limits of Power Quality emissions and the behavior at grid disturbances.
Picture
One System. All the Measurements

Testing according to these regulations requires a couple of different test procedures and different test equipment. The Dewesoft solution allows wide range analysis according to these standards with a single instrument.

Special factors like flicker step factor, voltage change factor, symmetrical components, period values for P, Q, S, U, I (for half-wave or full-wave) etc. are calculated in the software. The recorder allows creating all necessary graphs with the different parameters (e.g. P-f chart).

The data logging capability allows storing the raw data for analyzing the switching processes or the behavior at faults (Waveform analysis). The Math library can calculate any statistical parameter (e.g. max, active power for 0.2s, the 60s and 600s) and also offers the possibility to automatically check if the power generation unit meets the requirements.

6 x high-voltage analog inputs
6 x current analog inputs
1 x low voltage analog input for set point value
