Laboratory of Electrical Power Engineering 2

Course Description

The purpose of this course is introducing students to laboratory testing in high voltage (HV) laboratory:. Generation and measurement of alternating HV. Alternating corona discharge. Testing and measurements of voltage distribution along insulator strings. Breakdown in solid and liquid dielectrics. Measurement of solid and liquid dielectrics characteristics. Generation and measurement of direct HV. Electrical breakdown in gases. Spike - panel gap . Generation and measurement of impulse HV. Discharge voltages (50% values). Metal oxide arresters. Testing of insulating protection equipments. During this course students are also introduced to basics features of electricity market. Students are using MASI simulator which mimics real life exchange trading. Their decisions and system technical constraints impacts on realized profit are analised.

General Competencies

The students will participate in hands-on playing in the virtual electric power market (bidding, market rules, determining clearing price). The students should get acquainted with high voltage testing problems. They will get practical experience with generation, measurement and high voltage testing.

Learning Outcomes

  1. describe the importance of high voltage testing
  2. explain the purpose of certain types of high voltage tastings
  3. relate the test results with previous findings
  4. explain the way in which exchange electricity trading takes place.
  5. prepare trading bids regarding available assets
  6. estimate social welfare loss due to power network congestions
  7. identify and estimate input data needed for calculation of electrical equipment heat-up
  8. compute and analzye temperature increase in electric power cables
