IP PA system for a 500MW coal-fired power plant with boiler, turbine, and switchyard zones?

Industry: power plant | Architecture: IP

A 500MW thermal power plant is one of the most demanding environments for a PA system — extreme EMI from transformers, noise above 95dB in the turbine hall, and wide outdoor switchyards. The BNA 9000-i125-HA IP server with its Intel Xeon processor and RAID storage ensures uninterrupted operation even in power fluctuation scenarios. BNA 9100 SIP master stations in the central control room allow unit supervisors to page specific zones: boiler house, turbine hall, or switchyard independently. The BNA EI-4104 EPABX interface connects the PA system to the plant's intercom for seamless operator communication. BNA IP-H15-POE horn speakers are installed on vibration-isolated brackets in the turbine hall to overcome 95dB ambient noise. Integration with DCS alarm outputs enables automated pre-recorded announcements for tripping events.
