Tasirin Dabi na Tansufa a Makarantun Iyali da Turuwar UHVDC
Idan karamin iyali na tansufa na Ultra-High-Voltage Direct Current (UHVDC) yana cikin makarantun iyali na turuwa, zai iya haifar da ci gaba da ke faruwa a kan iyali. Wannan ci gaba da ke faruwa zai iya haifar da ci gaban neutral-point na tansufa daban-daban, wanda ke shafi DC bias (ko DC offset) a dukkun tansufa. Wannan DC bias zai iya rage muhimmanci na tansufa, kuma a wasu lokutan zai iya haifar da lalace-gabashin abubuwa. Saboda haka, ana bukatar masu sauki don inganta wannan abin da ke faruwa.
An bayyana wannan matsala a cikin bayanai:
1. Abubuwan Da Sune Muhimmiyar Tasir
Gaskiya ta DC bias yana da muhimmanci saboda abubuwan da suka biyo, ciki har da:
Gaskiya ta DC bias yana da muhimmanci saboda abubuwan da suka biyo, ciki har da:
- Ci gaban UHVDC system;
- Ingantaccen da kuma tasirin karamin iyali;
- Kafin da yawa da kuma gaskiya ta soil resistivity;
- Kudin da kuma tsarin dukkun tansufa.
2. Tasirin DC Bias
DC bias a tansufa zai iya haifar da:
DC bias a tansufa zai iya haifar da:
- Yawan nuna da kuma yawan mutum;
- Yawan tsumma saboda core losses;
- Yawan tsumma da kuma yawan tsumma da kusa da winding insulation a lokacin da ya yi waɗanda.
- Wannan abubuwa sun rage amfani da tansufa da kuma yawan tsumma da kusa da zuwa.
3. Masu Sauki Don Inganta Abin Da Ke Faruwa
Don inganta DC bias, ana iya amfani da wasu tattalin arziki:
Don inganta DC bias, ana iya amfani da wasu tattalin arziki:
- Dynamically switching the neutral grounding mode of the renewable energy station (e.g., between solidly grounded and high-resistance grounded);
- Optimizing the grounding grid design to balance potential distribution between the renewable plant and nearby substations;
- Installing DC-blocking devices (e.g., capacitive or active-type neutral blocking devices) at transformer neutral points to block geomagnetically induced or stray DC currents.

Tasirin DC bias a tansufa a makarantun iyali na turuwa da ke cikin karamin iyali na UHVDC yana da muhimmanci ga geoelectrical da power system issue wanda yana bukata hunhu. Ana raci a yi continuous monitoring of DC bias levels in affected transformers, conduct periodic risk assessments, and proactively deploy mitigation measures. Wannan zai taimaka da safe, stable, and long-term operation of renewable energy facilities within regions influenced by UHVDC systems.
