The proposed design utilize a cost-effective data acquisition using arduino in combination with LabVIEW software to implement the multi-purpose synchronizing relay. The proposed synchronizing relay is capable of synchronizing a Distributed Generator (DG) to the power grid from black-start and fulfills the requirements imposed by the utility. The synchronizing relay is implemented through voltage a","authors_text":"Babar Hussain, Khair-un-Nisa Fatima, Mariam Azam, Mishal Mahmood, Muhammad Abubakar, Muhammad Sarwar","cross_cats":["cs.SY","eess.SP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SY","submitted_at":"2019-06-30T08:51:00Z","title":"Design and Implementation of an Automatic Synchronizing and Protection Relay through Power-Hardware-in-the-Loop (PHIL) Simulation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.00339","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:bd50069b05c4906d12f1c2c38936d6e978e1706d19d24872c7f9b4a53d231c06","target":"record","created_at":"2026-05-17T23:41:52Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"b3bdcdac9de998a5756a87cb82022d9d2ca58bb8d824764f9ae64164f09f33f8","cross_cats_sorted":["cs.SY","eess.SP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SY","submitted_at":"2019-06-30T08:51:00Z","title_canon_sha256":"57c0fa73cc907fdf27f36019cad99b8dd38160d633c570c11b437f616c9cb9db"},"schema_version":"1.0","source":{"id":"1907.00339","kind":"arxiv","version":1}},"canonical_sha256":"5724d71725dc8455191334d3ed5d4208b217a0c0a9c762d33ebdf63e5795293b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5724d71725dc8455191334d3ed5d4208b217a0c0a9c762d33ebdf63e5795293b","first_computed_at":"2026-05-17T23:41:52.098512Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:41:52.098512Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ei0AYMjZ9xkzhJVmZm7tPQnmpBf2uSG3T1R0vy+v8I25QDjVDSwwySjLdgyUCU4C41BXlj8CIVLl3695iUGYBA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:41:52.099178Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.00339","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bd50069b05c4906d12f1c2c38936d6e978e1706d19d24872c7f9b4a53d231c06","sha256:707405f9f8964f9819706dfa933b6bf68d9674747036247570ab1e2765567b4e"],"state_sha256":"3413cc2f4cff4f720db385b3b0a937628a9ab3ecaa9f1fded5aaad6d04a67fb9"}
