Top Power Flow in HVDC Transmission MCQ Objective Questions
Power Flow in HVDC Transmission Question 1:
In case of a HVDC system, there is
Answer (Detailed Solution Below)
Neither charging current nor skin effect
Power Flow in HVDC Transmission Question 1 Detailed Solution
In case of DC, the charging current is totally absent then the length of transmission is not limited.
In case of DC, current is uniformly distributed hence skin effect is absent.
Power Flow in HVDC Transmission Question 2:
Two regional systems, each having several synchronous generators and loads are interconnected by an ac line and a HVDC Link as shown in the figure. Which of the following statements is true in the steady state:
Answer (Detailed Solution Below)
Power Flow in HVDC Transmission Question 2 Detailed Solution
As the two regions are interconnected by An AC line besides HVDC link, both regions must have same frequency.
We can control the power sharing between HVDC link and AC line by controlling converter station grid angle.Power Flow in HVDC Transmission Question 3:
Which of the following statement(s) is (are) true for homopolar HVDC link with ‘n’ no. of conductors having current I in each conductor.
- All conductors have same polarity.
- Half no. of conductor i.e. \({n \over 2}\) has same polarity and another half opposite polarity.
- Return path has zero current.
- Metallic return path cannot be used, only ground can be used as return path.
Answer (Detailed Solution Below)
i only
Power Flow in HVDC Transmission Question 3 Detailed Solution
Conductors in homopolar HVDC link have same polarity and return path can be ground as well as metallic both, which contain nI return current.
