1.0Ωresistance and 4.0Ω inductive reactance. It feeds a single-phase load having ZL=30Ω. Calculate
(a) the voltage drop across the source impedance and (b) the voltage across the load. If a PWM-based
SSSC (as shown in Figure below) is used to raise the voltage to the input voltage (230 V) with minimum
rating, then calculate (c) the voltage rating of the compensator, (d) the current rating of the compensator,
and (e) the VA rating of the compensator.

This Assignment corresponds to Unit No. / Lesson ………………5………………………….
1. Give the classification of UPQCs and explain Three-Phase Three Wire right shunt UPQC topology with
a schematic diagram along with corresponding phasor diagrams.
2. Explain the SRF based control algorithm for a Three-Phase Four Wire UPQC with a neat block diagram.
3. Obtain the design parameters for a Three-Phase Four Wire right shunt UPQC topology with a four-leg
VSC based DSTATCOM and DVR.
4. A single-phase unified power quality compensator (consisting of a DSTATCOM and a DVR using two
VSCs with a common DC bus capacitor) is to be designed for a load of 230 V, 50 Hz, 25 A, 0.8 lagging
power factor as a left-hand UPQC-Q (shown in Figure below). There is a voltage swell of +10% in the
supply system with a base value of 230 V. Calculate (a) the voltage rating of the DVR of the UPQC-Q,
(b) the current rating of the DVR of the UPQC-Q, (c) the VA rating of the DVR of the UPQC-Q, (d)
the voltage rating of the DSTATCOM of the UPQC-Q, (e) the current rating of the DSTATCOM of the
UPQC-Q, (f) the VA rating of the DSTATCOM of the UPQC-Q, and (g) total VA rating of the UPQC-
Q to provide reactive power compensation of the load for unity power factor at the AC mains with a
constant regulated voltage of 230V at 50 Hz across the load. (h) Draw the corresponding Phasor
diagrams.

Course/Subject: …Power Quality…Course Code..GR18D5049
Name of the Faculty: ……D Srinivas rao........................................……..Dept.: …EEE………
Designation: ASSISTANT PROFESSOR.
Guidelines to study the Course/ Subject: Power Quality
Course Design and Delivery System (CDD):
• The Course syllabus is written into number of learning objectives and outcomes.
• Every student will be given an assessment plan, criteria for assessment, scheme of evaluation
and grading method.
• The Learning Process will be carried out through assessments of Knowledge, Skills and
Attitude by various methods and the students will be given guidance to refer to the text books,
reference books, journals, etc.
The faculty be able to –
• Understand the principles of Learning
• Understand the psychology of students
• Develop instructional objectives for a given topic
• Prepare course, unit and lesson plans
• Understand different methods of teaching and learning
• Use appropriate teaching and learning aids
• Plan and deliver lectures effectively
• Provide feedback to students using various methods of Assessments and tools of Evaluation
• Act as a guide, advisor, counselor, facilitator, motivator and not just as a teacher alone
