Tip: If you only need a few specific solutions, request them from classmates or a study group. Sharing a single solution for personal study is generally considered fair use, but distributing the whole manual publicly is not.
Apply the relevant formulas and techniques to solve the problem. This may involve using mathematical models, such as:
$$P = V \cdot I \cdot \cos(\theta)$$
or
$$Q = V \cdot I \cdot \sin(\theta)$$
Problem (adapted from Chapter 4): Determine the voltage regulation of a 33 kV, 10 MVA load‑tap‑changing transformer supplying a lagging‑power‑factor load of 0.85, given that the transformer’s equivalent series impedance is Z = (0.05 + j0.45) pu.

Introduction
The CL Wadhwa Power System PDF is a popular resource for students and professionals in the field of electrical engineering, particularly those interested in power systems. The PDF provides a comprehensive overview of power system analysis, design, and operation. In this piece, we will focus on solution 11 of the CL Wadhwa Power System PDF, which deals with the analysis of power systems.
Problem Statement
Solution 11 of the CL Wadhwa Power System PDF deals with the following problem:
A 3-phase, 50 Hz, 400 km long transmission line has the following parameters:
The line is supplying a load of 500 MW at 0.8 power factor lagging. The receiving-end voltage is 220 kV. Find the sending-end voltage, current, and power factor.
Solution
To solve this problem, we can use the following steps:
The total line resistance per phase is: R = 0.1 Ω/km × 400 km = 40 Ω
The total line inductive reactance per phase is: X_L = 0.5 Ω/km × 400 km = 200 Ω
The total line capacitive reactance per phase is: X_C = 0.2 MΩ/km × 400 km = 80,000 Ω
The total line impedance per phase is: Z = R + jX_L = 40 + j200 Ω
The total line admittance per phase is: Y = 1 / (R + jX_L) = 1 / (40 + j200) S
The receiving-end power is: P_R = 500 MW
The receiving-end voltage is: V_R = 220 kV
The receiving-end current is: I_R = P_R / (√3 × V_R × pf) = 500 × 10^6 / (√3 × 220 × 10^3 × 0.8) = 1645 A
Using the transmission line equations, we can calculate the sending-end voltage and current:
V_S = V_R + I_R × Z = 220 × 10^3 + 1645 × (40 + j200) = 220 × 10^3 + 65780 + j329000 = 285.78 × 10^3 ∠ 48.5° V
I_S = I_R + V_R × Y = 1645 + 220 × 10^3 × 1 / (40 + j200) = 1645 + 535.45 = 2180.45 A
The sending-end power factor is: pf_S = cos(∠V_S - ∠I_S)
Using the calculated values of V_S and I_S, we can find the sending-end power factor.
Conclusion
In this piece, we have provided a step-by-step solution to problem 11 of the CL Wadhwa Power System PDF. The solution involves calculating the sending-end voltage, current, and power factor of a 3-phase transmission line supplying a load of 500 MW at 0.8 power factor lagging. The results can be used to analyze the performance of the transmission line and design suitable compensation equipment to improve the power factor and voltage profile.
