Integrated na Solusyon para sa Pag-optimize ng mga Sistemang Elektrikal ng Power Plant
Ⅰ. Pangunahing Layunin
Pataasin ang efisiensiya ng paggawa ng kuryente, tiyakin ang reliabilidad ng suplay ng kuryente, bawasan ang buong siklo ng operasyon na mga gastos, at makamit ang intelligent na regulasyon ng sistema ng kuryente.
Ⅱ. Mga Solusyon para sa Pagsasama-sama ng Core Subsystem
Dedicated Solution for Power Transformers
Analisis ng Sakit: Ang mga transformer ay nagsisilbing mahalagang hub para sa transmisyong elektriko, na nagbabawas ng 3%~5% ng kabuuang nawawalang enerhiya ng planta. Ang downtime na dulot ng pagkakasira ay nagdudulot ng kompletong brownout ng planta.
