Product Overview
The Woodward SPM‑D2‑10B/PSY5‑FU‑D‑W (8440‑2173) is a microprocessor‑based automatic generator synchronising unit for multi‑genset power‑generation systems. This panel‑mount synchroniser monitors generator and busbar voltage, frequency and phase‑angle difference, and outputs raise/lower pulse commands to generator governors and automatic‑voltage regulators to achieve matching conditions before circuit‑breaker closure. It includes two independent configurable parameter‑sets switchable via discrete input, supporting two different breaker‑closing time‑compensation profiles within one hardware unit. It addresses typical plant‑site pain points including manual synchronisation human error, inconsistent breaker‑closing timing for multiple generator assets, and limited adaptability for mixed‑prime‑mover fleets. Power‑plant commissioning engineers, marine‑power‑system technicians and stationary‑generation maintenance teams benefit from this unit. It supports synch‑check‑only mode, dead‑bus closing and isolated‑island‑mode frequency‑voltage regulation, and provides local LCD readout for real‑time electrical values, alarm status and parameter adjustment. It serves for new‑build power‑house integration as well as drop‑in replacement for legacy SPM‑D10 series synchronisers.
Application Scenarios
- Multi‑Unit Land‑Based Generator Paralleling Plants: Executes automatic synchronisation for diesel‑ and gas‑engine‑driven gensets connected to common busbars. Dual‑parameter‑set capability handles generators with differing breaker‑closing delays, optimising phase‑angle alignment at the moment of contact closure and limiting closing‑transient currents.
- Marine On‑Board Power‑Generation Systems: Installed inside ship power‑rooms for parallel‑operated auxiliary generator sets. Wide‑range power‑supply tolerance accommodates vessel‑board supply‑voltage fluctuation, and synch‑check interlock prevents out‑of‑phase breaker closure that risks generator winding damage.
- Combined‑Heat‑and‑Power Cogeneration Facilities: Manages generator synchronisation for engine‑driven CHP assets for grid‑parallel and island‑mode operation. It supervises voltage‑frequency matching before breaker closure and maintains stable isolated‑network regulation during utility‑grid loss events.
- Legacy Synchroniser Retrofit & Spare‑Part Replacement: Direct form‑fit upgrade for older SPM‑D10 synchronising hardware. The 96‑mm panel‑cutout footprint fits existing control‑panel cutouts, minimising mechanical‑modification work and shortening plant‑downtime during component swap‑out.
