PCH工程有多年的經驗設計風力渦輪機振動監(jiān)測器。的關鍵因素是要使用高精度和精密度高的過濾器,所以你監(jiān)控什么是重要的,并消除假警報。使用來自PCH工程的監(jiān)視器,您可以獲得最大值保護和高效率您的風力渦輪機在最危急的大風條件。不同的結構頻率成分往往在頻率尺度上分布非常緊密的。因此,過濾器必須具有高選擇性,以便只傳遞感興趣的頻率分量。簡單的過濾器在整個過程中都會出現問題頻率范圍和不會抑制結構共振在更高頻率范圍內的頻率,盡管它們是預計。這會導致錯誤或過早的警報停機時間。頻率響應很重要,但是還有時域響應,比如時延,相位和暫態(tài)響應是重要的參數。PCH工程有多種類型和訂單的濾波器以滿足頻域和時域響應之間的折衷要求。高精度濾波器PCH工程的所有課程都是選擇性通過的頻率源于頻帶內感興趣的結構分量并抑制所有非頻段外有趣的頻率。
智能保護系統(tǒng)永遠值得信賴從PCH工程,從而最大化即使在最惡劣的風力下,風力渦輪機的運行時間條件。

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.
