Solution Reliability Evaluation Of Engineering Systems By Roy Billinton And [exclusive]

Draw your system as a Reliability Block Diagram (RBD) – series vs. parallel.

| Index Category | Specific Index | Definition (Billinton’s phrasing) | | :--- | :--- | :--- | | | LOLP | Probability that the load will exceed available capacity at a given time. | | Frequency | LOLE | Expected number of days (or hours) per year that a deficiency exists. | | Duration | LOLD | Average duration of each deficiency event. | | Energy | EENS | Expected Energy Not Supplied (in MWh). Used for economic costing of failures. | | Customer | SAIFI | System Average Interruption Frequency Index (customer-centric). | | Customer | CAIDI | Customer Average Interruption Duration Index (restoration speed). | Draw your system as a Reliability Block Diagram
