Russelectric, a Siemens business that manufactures power control systems and automatic transfer switches, describes the benefits of centralized paralleling systems for applications that need precise control, high reliability and operational visibility.
Unlike onboard paralleling, where synchronization and control components are mounted on or near each generator, centralized architectures centralize key control functions in a dedicated switchgear environment. This approach supports hot-standby PLCs, manual backup control, discrete analog metering and event logging. These features help maintain continuous power for mission-critical facilities like hospitals, data centers and industrial campuses.
Centralized systems offer increased redundancy and scalability, allowing operators to monitor and manage the generator from a centralized, climate-controlled control room away from engine rooms that may be hot and exposed to diesel particulates. Real-time synchronization logic, configured with narrower tolerances and faster response, reduces mechanical stress on generator breakers and supports smoother transitions during load changes.
In contrast, onboard solutions are typically used in smaller installations and may provide less redundancy and fewer manual control options, often using vendor-specific logic and inter-controller communications.
