  1. DISTRIBUTED GENERATION EFFECTS ON PROTECTIVE RELAYING APPLICATIONS

  2. INNOVATIVE PROTECTION FEATURES • Microprocessor Based Programmable Protection Systems • Inputs, Outputs and Operator Controls • Digital relay-relay communications • Disturbance data capturing and sequential event reporting

  3. INPUTS AND OUTPUTS • Inputs Provide Protection System and Equipment Status • Outputs Provide Interconnection Functionality • Trip and close control • Inadvertent utility energization interlocks

  4. PROGRAMMABLE OPERATOR CONTROLS Interconnection Control Functionality can be Easily Changed via Operator Control Programming

  5. DIGITAL RELAY-RELAY COMMUNICATIONS • Enables Advanced Feeder/Distributed Generation Control • Direct transfer trip initiated from feeder recloser • Distributed generation control based on feeder recloser loading • Distributed generation status provided to feeder recloser

  6. SEL MIRRORED BITS Communications

  7. Transmit “Mirrored” to Receive

  8. Recloser to DG UnitMIRRORED BIT Communication

  9. CONCLUSIONS • Programmable Protection Systems will Provide Flexibility for Future Distributed Generation Control • Digital Relay-Relay Communications will Enable Feeder Control of Distributed Generation • Programmable Operator Controls will Allow Routine Functionality Changes via Front Panel Push Button Control • Interconnection System Enhanced by Programmable Output
