Question

When the bus k is a load bus with no generation and inductive load, in terms of generation and load, ${\mathbf{P}}_{\mathbf{k}}$= __________, and${\mathbf{Q}}_{\mathbf{k}}$= __________.

Short answer

When the bus k is a load bus with no generation and inductive load, in terms of generation and load, ${\mathrm{P}}_{\mathrm{k}}=-{\mathrm{P}}_{\mathrm{LK}}$and ${\mathrm{Q}}_{\mathrm{K}}=-{\mathrm{Q}}_{\mathrm{LK}}$.

Step-by-step solution

Determine the Power Flow Program

The bus k is a load bus with no generation, ${\mathbf{P}}_{\mathbf{k}}\mathbf{=}\mathbf{-}{\mathbf{P}}_{\mathbf{L}\mathbf{K}}$ is negative; that is, the real power supplied to bus k. If the load is inductive,${\mathbf{Q}}_{\mathbf{K}}\mathbf{=}\mathbf{-}{\mathbf{Q}}_{\mathbf{L}\mathbf{K}}$ is negative.

Determine the answer.

The bus kcould be aload bus with no generation,${\mathrm{P}}_{\mathrm{k}}=-{\mathrm{P}}_{\mathrm{LK}}$ is negative;that’s, the real power supplied to bus k. If the load is inductive,${\mathrm{Q}}_{\mathrm{K}}=-{\mathrm{Q}}_{\mathrm{LK}}$ is negative.

Therefore, the complete statement is “When the bus k is a load bus with no generation and inductive load, in terms of generation and load, ${\mathrm{P}}_{\mathrm{k}}=-{\mathrm{P}}_{\mathrm{LK}}$and ${\mathrm{Q}}_{\mathrm{K}}=-{\mathrm{Q}}_{\mathrm{LK}}$”.
