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 of 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 and reactive power, the limits of Power Quality emissions, and the behavior at grid disturbances.
Testing according to these regulations requires a couple of different test procedures and different test equipment (Scope, Power Analyzer, Data Logger, Analysis software, and mathematical operations). 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 the creation of 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.
