PCH Engineering has many years of experience designing vibration monitors for wind turbines. The key factor is to use high precision and precision filters, so you monitor what is important and eliminate false alarms. Using monitors from PCH Engineering, you can get maximum protection and high efficiency for your wind turbine in the most critical wind conditions. The different structural frequency components tend to be very tightly distributed on the frequency scale. Therefore, the filter must be highly selective in order to transmit only the frequency component of interest. Simple filters will present problems throughout the frequency range and will not suppress structural resonances at frequencies in the higher frequency range, although they are expected. This can lead to errors or premature alarm downtime. The frequency response is important, but there are also time domain responses, such as time delay, phase and transient responses that are important parameters. PCH Engineering has multiple types and orders of filters to meet the tradeoff between frequency domain and time domain response. All courses in PCH Engineering are selective to pass frequencies derived from structural components of interest within the frequency band and suppress all frequencies of interest outside the frequency band.
Intelligent protection systems can always be trusted from PCH engineering, thus maximizing wind turbine operating time conditions even in the harshest winds.
