The electrical distribution network mainly comprises of 11kV & 0.4kV systems. The main power source is 11kV supply from WAPDA, which is step downed to 0.4kV via 750kVA transformer. In absence of WAPDA supply, the plant is equipped with generators G-01 (550kVA) & G-02 (110kVA). Both are connected at MDB-001 @ 0.4kV. The downstream of MDB-001 consists of MCCs, power panels, lighting DBs etc to feed the plant auxiliaries. Scope is to conduct power system studies for the power generation and distribution system of APL Terminals. Following studies were performed:
• Load Flow Study
• Short Circuit Study
• Motor-Starting Study
• Protection Coordination Study
• Arc Flash Study
