SEL Microcomputer Protection Device SEL587 Series from the United States
Model: PN058710C2132
1、 Overview of SEL microcomputer protection device in the United States
The SEL-587 generator protection relay is a solution for protecting utility and industrial generators through automatic synchronization devices, flexible I/O, and * communication. By using SEL-587 relays, comprehensive generator primary and backup protection can be provided. SEL-587 provides comprehensive protection and synchronization solutions for synchronous generators. Eliminated complex and expensive independent synchronizer components. Integrating the synchronization function into the generator protection relay can provide a cost-effective and reliable solution. No need to cut or drill holes in existing incisions, as long as small components and multiple installation adapters are used, protection can be easily upgraded. Modbus, DNP3, IEC61850, mirror bit communication, DeviceNet, and other protocols can be quickly integrated into serial - or Ethernet based communication, making communication easy - choose single or double stranded copper wire or fiber Ethernet ports, or serial communication devices, and select multiple protocols including MirroredBits communication and IEC61850. Choose multiple Modbus TCP or Modbus continuous sessions to customize your application configuration. Utilize DNP3 serial or DNP3LAN/WAN protocol.
The comprehensive generator protection-SEL-587 generator protection relay can be applied to large, medium, and small generators to provide complete protection for both the main and backup generators. The SEL-587T provides a generator grid protection solution that complies with IEEE1547 for distributed power generation. Adding a neutral point voltage connection can provide 100% stator grounding protection based on third harmonic voltage measurement. Connecting the neutral wire current input can provide protection for machines that are directly grounded or resistor grounded. Automatic synchronization - using the built-in automatic synchronizer function to replace external generator control and synchronizer relays. The frequency, voltage, and phase control functions of the generator are used to achieve automatic synchronization and grid connection with the power system. The generator start-up report and PC synchronous oscilloscope are used to monitor the synchronization process of the generator. Current differential protection - sensitive ratio braking current differential elements and differential quick break elements, as well as synchronous inspection and overexcitation detection (V/Hz), are used throughout the device to protect the generator and booster. The optional current differential component detects stator faults through a safe and sensitive current differential function. The power transformer and CT connection compensation allow the booster of the device to be included in the differential protection zone of the generator.
2、 Design concept of SEL microcomputer protection device in the United States
1. Comprehensive generator protection
A large number of current, voltage, frequency, distance, power, and out of step components can provide comprehensive protection for large, medium, and small generators.
2. Automatic synchronization
The optional built-in automatic synchronizer function eliminates expensive external synchronization devices. The frequency, voltage, and phase control of the generator are automatically synchronized and connected to the power system.
3. Easy to communicate
Choose single or double stranded copper wire or fiber optic Ethernet ports, or serial communication devices, and select multiple protocols including MirroredBits communication and IEC61850. Choose multiple Modbus TCP or Modbus serial sessions to customize your application configuration. Utilize DNP3 serial or DNP3LAN/WAN protocol.
4. Stator grounding detection
The SEL-587 uses traditional neutral point overvoltage components with third harmonic voltage difference detection to detect stator grounding faults in high impedance grounded generators.
5. Current differential protection
The optional current differential component detects stator faults through a safe and sensitive current differential function. The power transformer and CT connection compensation allow the inclusion of the booster in the differential protection zone of the generator.
6. Power components
Sensitive power components provide protection against reverse power, overload conditions, or forward low power.
7. RTD basic thermal protection
Use 10 internal RTD input cards or an external SEL-2600RTD module to collect temperature data for the SEL-587 alarm, monitoring, and trip functions
8. Measurement and reporting
View the automatic synchronizer, continuous event recorder (SER), and 180 cycle oscilloscope event report of the generator, and analyze the generator's startup, shutdown, or system faults. Measure electrical, thermal, and generator operating parameters.
9. Synchronize phasor data
Using SEL synchronous phasor (IEEEC37.118), convert state estimation into state measurement and issue possible system instability alerts in advance. The measurement accuracy of SEL-587 phasor meets the requirements of IEEE C37.118-2005 Level 1.
The SEL-587 provides comprehensive generator protection for both main and backup generators, supporting various applications of small, medium, or large generators. Neutral point voltage input can provide stator grounding protection based on fundamental and third harmonic zero sequence voltage measurements. The neutral point current input provides direct grounding or grounding protection through a transition resistor. The built-in automatic synchronization function of automatic quasi synchronization can replace additional generator control and quasi synchronization relays. The frequency, voltage, and phase control of the generator are automatically synchronized and connected to the power system. The generator start-up report and PC synchronization indication can be used to monitor the generator synchronization process. The sensitive percentage rate braking current differential protection element and differential breaking element, in conjunction with synchronous detection and overexcitation element, provide complete protection for the generator boost converter group. The optional current differential component provides safe and sensitive current differential function for detecting stator faults. The compensation of power transformer and CT wiring allows the step-up transformer to be included in the differential area of the generator. SEL-587 provides a complete protection and synchronization solution for synchronous generators. It eliminates the need for complex and expensive independent generator synchronization equipment. Integrating automatic synchronization function into generator protection relays can provide an economical and reliable solution.
The optional SEL-2664 rotor contact protection module detects rotor ground faults regardless of whether the generator is in operation, shutdown, or idle state.
