Past practices of power factor correction combined with new solid state control equipment have put many of our power systems at risk. Failures and losses due to harmonic heating and resonant harmonics are just some of the problems that have become common. The HI_WAVE Study module helps you examine and reduce these harmonic disturbances. With HI_WAVE, new power systems can be examined before they are built and the harmonic effects addressed during the design. Existing power systems can be studied and corrective filter designs evaluated before they are installed. Every point and branch in the power system can be quickly evaluated for harmonic content and for resonant impedance characteristics.

 

HI_WAVE plots distortion waveforms, distortion spectra, scan magnitudes, and scan angles, and includes a user-customisable Library for accurate modelling of almost any harmonic source that you encounter in your system. Harmonic sources can be defined at multiple bus locations throughout the power system. Capacitor banks and filters can be included in the voltage and current distortion evaluation, in impedance resonance scans and in harmonic load flow results.

HI_WAVE uses state-of-the-art sparse matrix and current injection methods for fast and accurate solutions. Harmonic currents are injected into the system at the harmonic source locations to investigate the self and mutual responses of the system during the frequency scan simulation. Filter parameter calculations are provided to interactively assist the user in harmonic distortion elimination. HI_WAVE's unique modelling techniques provide the most rigorous solutions available.

As with all PTW Study modules, HI_WAVE uses the same database, so you can examine all your existing Projects.
