Product Description
DG Diesel Generator set synchronizing is a process that allows multiple generators to operate in parallel sharing the load effectively while maintaining system stability This is crucial for applications requiring continuous power supply especially in critical facilities Heres a technical description of the DG set synchronizing process
Components
1 Diesel Generators
Multiple DG sets configured to operate in parallel
2 Synchronizing Panel
Contains the control logic and circuitry needed for synchronizing generators This panel typically includes
Synchronizing Relays Monitor voltage frequency and phase angle
Load Sharing Controllers Ensure that each generator contributes to the load proportionally
Control Switchgear For manual or automatic operation of circuit breakers
3 Voltage and Frequency Measurement Devices
Instruments to measure the output voltage frequency and phase of each generator and the bus bar
4 Phase Sequence Indicators
Tools to ensure that generators are in the correct phase sequence before synchronization
5 Communication Interface
Allows for data exchange between generators and control systems enabling coordinated operation
6 Protection Devices
Circuit breakers and fuses for overcurrent shortcircuit and underovervoltage protection
Synchronization Process
1 PreSynchronization Checks
Verify that all generators are operating under similar conditions voltage frequency phase sequence
Ensure that the bus bar voltage is stable and within acceptable limits
2 Matching Parameters
Adjust the speed and voltage of the incoming generator to match those of the bus bar
Use the governor control for speed adjustment and the voltage regulator for voltage alignment
3 Phase Synchronization
Ensure that the phase angle of the incoming generator matches that of the bus bar This is critical to prevent circulating currents
Phase comparators in the synchronizing panel assist in determining phase alignment
4 Connection
Once parameters are matched and synchronized the circuit breaker of the incoming generator is closed connecting it to the bus bar
Load sharing controllers then adjust the output of each generator to balance the load
5 Load Management
Continuous monitoring and adjustment of each generators output to ensure balanced load sharing and system stability
Applications
Used in various industries including telecommunications hospitals data centers and manufacturing where reliable and uninterrupted power supply is critical
Advantages
Increased reliability by providing backup power through multiple sources
Enhanced efficiency through optimal load sharing
Flexibility to add or remove generators based on load demand without interruption
Standards
Compliance with relevant standards and regulations for electrical installations eg IEC NEMA UL to ensure safe and reliable operation
