6 FAQs about [Dynamic analysis of capacitor grounding]

Do grounding systems affect functional characteristics of DC-systems?

Also, a complete set of functional characteristics of DC-systems are introduced and elaborated, and accordingly, the impact of grounding systems on the functional characteristics are analyzed from various technical perspectives.

Which section introduces existing grounding strategies in DC electrical systems?

Section 2 introduces existing grounding strategies in DC electrical systems. A full description and definition of CM voltage and its behavior considering different grounding strategies are given in Section 3. Section 4 lights on the concept of stray current and its consequences.

How does cm voltage affect a grounding system?

The voltage of every pole with respect to the ground is highly oscillatory which indicates a considerable amount of CM voltage. As shown in Fig. 11 (b), by the occurrence of an LG fault, the fault loop is not formed in this grounding system. Then, the transient overcurrent does not happen under fault conditions, and the fault current is zero.

What are the benefits of mid-point grounding with resistors and capacitors?

Through the analysis, it is considered that mid-point grounding with resistors and capacitors has many benefits, such as better human safety and system protection. A low voltage DC (LVDC) system has higher energy efficiency than an AC system and can minimize power conversion loss caused by the integration of renewable energy sources [ 1, 2, 3 ].

Does a grounding strategy affect functional characteristics?

According to the evaluations carried out in the former sections, the impact of each grounding strategy on the functional characteristics including CM voltage, stray current, fault detection, fault ride-through capability, and also fault responses is comprehensively investigated.

Can a DC grounding system ride through LL faults?

The ungrounded, high resistance grounded and bipolar low resistance grounded systems are capable of riding through the LG faults. It should be noted that none of the grounding schemes provides the FRT capability under LL faults. The paper presents a comprehensive review on the topic of DC grounding systems.
