Solutions | Synchronizing Systems

Beckwith Electric’s Synchronizing Systems are suitable for the automatic synchronizing of a generator to the electric power network. The system provides speed and voltage “jogs” to bring a generator to proper conditions of matching  voltage and frequency, prior to safely and  accurately closing a breaker into a bus energized by an electric power network. They offer the best accuracy in the industry to assure safety for your most expensive asset.

• Facilitates standardization for generator and system intertie sync check applications
• Assure safe and accurate connection of a generator to the power network
• Provides accuracy and independent controls; no additional instrumentation is required for field setting
• Breaker closing times are field programmable
• Local and remote serial communications (MODBUS protocol) capability for monitoring and control functions

• Unit can be multiplexed to different generators that have different breaker closing times.
• An infinite amount of different breaker closing times can be obtained by simple contact closures to the relay.
• Accurate, independent controls require no additional instrumentation for field setting
• Various ∆V and ∆F limits available
• Breaker closing times are field programmable
• 50 Hz operation available

• Matches Generator Speed And Voltage To System
• Works In Conjunction With M‑0193B Syncrocloser® Unit To Close Breaker At Zero Degrees Phase Angle Error
• Adjustable Jog Durations, proportional to error, for Voltage and Speed control.
• Time Between Jogs adjustments bring the generator to a matched condition in minimum time and eliminate overshoot and hunting.
• Kicker Pulse brings phase angle around through zero if speed is matched but synchronism has not yet occurred. Adjustable pulse duration compensates for the sensitivity of the governor.

• Accurate, independent controls require no additional instrumentation for field setting
• Voltage limit ranges and dead line/dead bus closing features are optional
• Remote contacts to shift phase angle or time setpoints are standard
• Transducer analog outputs are SCADA compatible

• Enhances system stability when applied to transmission and primary distribution reclosing schemes
• Detects a static phase angle across an open breaker in 0.5 second to assure a fast permissive for reclosure
• Simultaneously measures voltage magnitudes to ensure that they are within upper, lower and difference limits
• Includes dead line/dead bus closing features
• Remote command widens the phase angle setpoint to respond to system emergencies or to narrow the setpoint when the two systems are isolated to close the breaker very close to 0°
• Transducer analog outputs are SCADA compatible
