Question
Perform a detailed voltage analysis in the given medium-voltage 6-node radial power system example. Reflect on voltage drops, power losses and line efficiency for your given consumption, for consumption that is 25% higher and consumption that is 25% lower.
Then repeat all 3 analyses if the consumption at node 5 is with power factor of 1.
Analyse and discuss the sensitivity of voltage drop [in % of amplitude] and with respect to the current level and the power factor.
Identify the maximal generating power (MW only) that your network can accept in a single node without voltage in any node exceeding 1.05 p.u.
