SCHEDULE 3—INTERCONNECTION PROCESS,TECHNICAL REQUIREMENTS,AND OPERATING PROCEDURES <br /> (1)Any time the interface hardware or software, including protective relaying and generation control <br /> systems are replaced and/or modified, the Area EPS operator shall be notified. This notification <br /> shall, if possible, be with sufficient warning so that the Area EPS personnel can be involved in the <br /> planning for the modification and/or witness the verification testing. Verification testing shall be <br /> completed on the replaced and/or modified equipment and systems.The involvement of the Area <br /> EPS personnel will depend upon the complexity of the Generation System and the component <br /> being replaced and/or modified. Since the Interconnection Customer and the Area EPS operator <br /> are now operating an interconnected system. It is important for each to communicate changes in <br /> operation, procedures and/or equipment to ensure the safety and reliability of the Local and Area <br /> EPSs. <br /> (2)All interconnection-related protection systems shall be periodically tested and maintained, by the <br /> Interconnection Customer, at intervals specified by the manufacture or system integrator.These <br /> intervals shall not exceed 5 years. Periodic test reports and a log of inspections shall be <br /> maintained, by the Interconnection Customer and made available to the Area EPS operator upon <br /> request. The Area EPS operator shall be notified prior to the period testing of the protective <br /> systems,so that Area EPS personnel may witness the testing if so desired. <br /> (a)Verification of inverter connected system rated 15kVA and below may be completed as <br /> follows; The Interconnection Customer shall operate the load break disconnect switch and <br /> verify the Generator automatically shuts down and does not restart for at least 5 minutes <br /> after the switch is close <br /> (b)Any system that depends upon a battery for trip/protection power shall be checked and <br /> logged once per month for proper voltage. Once every four years the battery(s) must be <br /> either replaced or a discharge test performed. Longer intervals are possible through the use <br /> of"station class batteries"and Area EPS operator approval. <br /> Interconnection Process for Distributed Generatic Systems <br />
