Description

Woodward SPM‑D11 8440‑1666/E‑Generator Synchronizing & Load Sharing Unit

Product Overview

SPM‑D11 8440‑1666/E is a digital synchronizing and load distribution controller for generator sets, designed for parallel grid‑connection operations. It measures voltage, frequency and phase‑angle differences between generator and busbar, executing automatic close‑in commands for circuit‑breaker closure. This unit mitigates unstable paralleling risks, prevents out‑of‑phase switching damage, and stabilizes load sharing for multiple generator groups in isolated or grid‑tied power systems.
