Q5. Assume that the following permanent outage data has been given for the system shown below: System Component Outage Rate Average (outages/yr) Repair Time(h) 138KV 69kV 138KV breakers 138KV Line 138/69Kv transformer 69Kv breakers 69Kv bus 0.0058 66 0.627 10 0.0119 0.0045 0.011 360 44 Assuming that 132Kv bus is 100% reliable and determine the following: a. Total failure rate for one parallel line. b. Total mean time to repair for one parallel iine. c. Total failure rate of the system. d. Total mean time to repair of the system.
Short Transmission Line
A short transmission line is a transmission line that has a length less than 80 kilometers, an operating voltage level of less than 20 kV, and zero capacitance effect.
Power Flow Analysis
Power flow analysis is a topic in power engineering. It is the flow of electric power in a system. The power flow analysis is preliminary used for the various components of Alternating Current (AC) power, such as the voltage, current, real power, reactive power, and voltage angles under given load conditions and is often known as a load flow study or load flow analysis.
Complex Form
A power system is defined as the connection or network of the various components that convert the non-electrical energy into the electric form and supply the electric form of energy from the source to the load. The power system is an important parameter in power engineering and the electrical engineering profession. The powers in the power system are primarily categorized into two types- active power and reactive power.
