- SCOPE OF WORK
Purpose: The purpose of this program is to enhance the capacity of the Rwanda Energy Group (REG) for reliable and efficient operation of Rwanda’s national electric grid, reducing outages and interruptions and further stabilizing the grid. The program will help ensure that:
- REG has sufficient black start capabilities to restore the Rwandan electric grid from a total or partial shutdown in the shortest time possible;
- REG’s protection systems are set up to operate with the necessary reliability and security; and
- There is sufficient integration of power system stabilizers to attenuate disturbances and increase an overall stability of the grid.
Objectives: The objectives of this program shall include the following:
Issue 1 – Black Start Plan: to perform a comprehensive audit of REG’s Black Start Plan, identify deficiencies and potential problems, and provide technical solutions and recommendations for improvement.
Issue 2 – Protection Coordination (transmission lines, transformers, distribution): to perform a comprehensive review of REG’s current transmission and distribution protection systems to ensure that protective devices are coordinated to insure minimal outage exposure, identify deficiencies and potential problems, and provide technical solutions and recommendations for improvement.
Issue 3 – Integration of Power System Stabilizers (PSS): to conduct a comprehensive assessment of the integration of power system stabilizers, identify deficiencies and potential problems, and provide technical solutions and recommendations for improvement.
Tasks: The tasks to be performed by the Consultant under this Scope of Work shall include the following:
Task 1: Preliminary review of documents: Conducting a preliminary review of all relevant data and documents.
Task 2: Technical meetings in country: 5-days will be allowed for technical review meetings (including site visits, if necessary) to collect and verify required data and to discuss approaches and system operation procedures with EUCL engineers and executives.
Task 3: Conducting a comprehensive audit of REG’s Black Start Plan, including line/cable charging strategies, protective systems and general restoration policies.
Task 4: Performing a comprehensive review of REG’s current transmission and distribution relay protection coordination.
Task 5: Conducting a comprehensive assessment of the effectiveness of integrated power system stabilizers in enhancing the stability of the national grid.
Task 6: Satisfactory submission of a draft report on Black Start Plan: Electronic submission, in English, of a draft copy of the Black Start Plan Audit Report to USEA for USEA and REG review.
Task 7: Satisfactory submission of a draft report on Relay Protection Coordination: Electronic submission, in English, of a draft copy of the Relay Protection Coordination Review Report to USEA for USEA and REG review.
Task 8: Satisfactory submission of a draft report on Power System Stabilizers: Electronic submission, in English, of a draft copy of the Report on Review of Integration of Power System Stabilizers to USEA for USEA and REG review.
Task 9: Satisfactory submission of the final report on Black Start Plan: Electronic submission, in English, of the final copy of the Black Start Plan Audit Report incorporating USEA and REG’s comments.
Task 10: Satisfactory submission of the final report on Relay Protection Coordination: Electronic submission, in English, of the final copy of the Relay Protection Coordination Review Report incorporating USEA and REG’s comments.
Task 11: Satisfactory submission of the final report on Power System Stabilizers: Electronic submission, in English, of the final copy of the Report on Review of Integration of Power System Stabilizers incorporating USEA and REG’s comments.
