Wani da za suka faruwa a lokacin da aka saka AC microgrid zuwa DC distribution system?

Idan kofin daɗi mai girma na AC zuwa cikin sabisar daɗi mai tsakiyar DC, za su iya samu matsaloli. Haka ita ce bayani mai zurfi game da waɗannan abubuwa:

1. Matsalolin Daɗi Mai Tsayi

• Kadangunan Daɗi Mai Tsayi da Karkashinsa: Kadangunan daɗi mai tsayi a cikin girmamai AC zai iya tabbatar da karkashinsa sabisar daɗi mai tsakiyar DC. Sabisar daɗi mai tsakiya sun fi yiwuwa da ma'ana a kan karkashin daɗi mai tsayi, saboda haka duka kadangunansa zai iya haifar da tattalin aiki ko kasa kayan aiki.

• Zafiya ta Harmonics: Kayan aiki mai lafiya a cikin girmamai AC zai iya gina harmonics, wanda suke zama zafiya a cikin sabisar daɗi mai tsakiya ne a kan inverters, wanda ke haifar da tsayin daɗi mai tsayi a cikin sabisar daɗi mai tsakiya.

2. Matsalolin Aikinsa da Ingantaccen Aiki

• Ingantaccen Aikinsa: Tattalin aikinsa ga girmamai AC da sabisar daɗi mai tsakiyar DC suna da yanayi, saboda a girmamai AC ana bukata don in yi amfani da frequency da phase control, amma a sabisar daɗi mai tsakiya ana yi amfani da voltage control. Idan an sa shi biyu, zai haifar da ingantaccen aikinsa, ya kamata a yi takarda masu inganci.

• Ingantaccen Ingantaccen Aiki: Ingantaccen ingantaccen aiki ga girmamai AC da sabisar daɗi mai tsakiya suna da yanayi, saboda a girmamai AC ana yi amfani da circuit breakers da relays, amma a sabisar daɗi mai tsakiya ana bukata don in yi amfani da kayan aiki masu ingantaccen aiki daɗi mai tsakiya. Ingantaccen ingantaccen aiki ga shi biyu ana buƙace don in yi takarda don in ba da amsa mai sauƙi da ingantaccen aiki idan an samu abin daɗi.

3. Matsalolin Daidaituwar Kayan Aiki

• Inverters da Rectifiers: Ana bukata don in yi daidaituwar bayan girmamai AC da sabisar daɗi mai tsakiyar DC a kan inverters da rectifiers. Aikin da tattalin aikin daɗi mai tsayi suka haifar da aikin daɗi mai tsayi na baki. An buƙace don in yi takarda inverters da rectifiers don in ba da amsa mai sauƙi da daidaituwar energy flow mai biyu da tattalin aikin daɗi mai tsayi.

• Sabisar Energy Storage: Girmamai AC suna da sabisar energy storage, wanda ana bukata don in yi daidaituwar da take-girman daidaituwar bayan an sa shi a cikin sabisar daɗi mai tsakiya don in ba da amsa mai sauƙi da tattalin aiki da karkashinsa.

4. Matsalolin Arzikin da Cost

• Cost of Equipment: Samun inverters da rectifiers zai haifar da cost of initial investment of the system. Amma, complex control systems da protective equipment zai haifar da operation and maintenance costs.

• Operating Costs: Bidirectional energy flow da daidaituwar daidaituwar daidaituwar zai haifar da loss of energy, wanda ke haifar da operating costs of the system.

5. Matsalolin Yakin Aiki

• Yakin Aiki: Yakin aiki ga girmamai AC da sabisar daɗi mai tsakiya suna da yanayi, saboda haka, an buƙace don in yi takarda yakin aiki ga shi biyu. Abin daɗi a kowace mafi yawa zai iya haifar da tattalin aiki ga duk system.

• Propagation of Faults: Abin daɗi a cikin girmamai AC zai iya haifar da sabisar daɗi mai tsakiya a kan inverters da rectifiers, kuma na biyu. Wannan ana buƙace don in yi takarda effective fault isolation and recovery mechanisms.

6. Matsalolin Standards and Specifications

Lack of Uniform Standards: Yanzu, standards and regulations for AC microgrids and DC distribution systems ba su fi yau da ƙananan. Systems connecting the two need to adhere to different standards, which may lead to compatibility and interoperability issues.

To sum up, when connecting an AC microgrid to a DC distribution system, it is necessary to take into account various aspects such as power quality, control and protection, equipment compatibility, economy, reliability, and standard specifications. Solving these issues requires interdisciplinary collaboration and technological innovation.
