Apakah itu Sistem Kuasa Berdaya Tahan?

Sistem kuasa berdaya tahan ialah infrastruktur elektrik yang dikhaskan untuk memastikan bekalan elektrik dihidupkan semasa bekalan elektrik terputus secara tiba-tiba. Semasa bencana alam, ribut, dan siklon, gangguan bekalan elektrik berlaku dalam grid utiliti.

Sistem Kuasa Berdaya tahan bertindak pada masa itu dan memulihkan bekalan elektrik kepada sistem tanpa sebarang gangguan. Mereka meramalkan, rancangan, dan memulihkan bekalan elektrik untuk pengguna.

Contoh Dunia Nyata

Katakan a 300 Hospital bekalan kuasa kW mengalami ribut atau serangan siber secara tiba-tiba. Grid mendapat gangguan yang membawa kepada pemberhentian tindakan utama:

• Bilik bedah ditutup.
• Mesin MRI/CT tidak lagi berfungsi.
• Tiada sistem lampu dihidupkan kerana gangguan.

Dalam kes sedemikian, sistem kuasa berdaya tahan ada untuk memulihkan keseluruhan bekalan dengan semua komponennya yang berbeza.

Komponen Sistem Kuasa Berdaya Tahan

Adakah anda tahu bagaimana sistem kuasa berdaya tahan berfungsi? Ia bergantung pada pelbagai komponen untuk mekanisme kerjanya. Mari kita mempunyai senarai komponen utama.

Sambungan Grid Utiliti

Jika anda tidak mahu kebebasan tenaga atau mahu menjimatkan wang dengan pemeteran bersih, sambungan grid utiliti harus ada. Ia membekalkan tenaga semasa gangguan tenaga boleh diperbaharui.

Berikut adalah beberapa perkara yang perlu diketahui.

• Penutupan grid boleh menyebabkan seluruh sistem ditutup untuk keselamatan.
• Gunakan dasar pemeteran bersih untuk memberi makan kepada grid semasa pengeluaran tenaga yang berlebihan dan dapatkan tenaga semasa gangguan sistem.

Sistem Penyimpanan Bateri

Sistem storan bateri ialah bekalan sandaran utama selepas gangguan grid utiliti atau ketiadaan tenaga suria. Ia melakukan tugas-tugas berikut.

• Membantu menyimpan tenaga dalam DC dan menggunakan penyongsang untuk menyuapkannya ke peranti.
• Membekalkan tenaga segera kepada sistem tanpa gangguan.
• Bateri litium-ion tahan lama, lebih cekap, dan menyediakan bekalan tenaga.

Diesel/Gas Penjana

Apakah yang akan anda lakukan jika bateri anda kehabisan tenaga? Selepas nyahcas bateri, anda mempunyai sumber tenaga yang tidak berkesudahan.

Ia adalah penjana diesel. Berikut adalah beberapa ciri utama:

• Mereka tidak dilepaskan dan memberikan tenaga sepanjang proses.
• Generators feature an endless supply as long as the fuel is available.
• You have to maintain them for high performance and operate at 70-85% load for fuel efficiency.

Renewable Energy Sources

There are several types of energy resources used nowadays. The most common methods for renewable energy are:

• Solar power
• Wind power

Solar power is being used on a large scale due to instant energy availability during the daytime. There are a few benefits of renewable energy resources.

• The source is unlimited. Oleh itu, there is no worry of running out of energy.
• It is an eco-friendly energy production setup.
• There are no carbon emissions or footprints.

Pengawal Microgrid

The microgrid controller is the brain of the

sistem. It performs various tasks during this energy production and usage. Here are a few tasks:

• Ia menyokong penjanaan tenaga boleh diperbaharui dan memantau beban.
• Memindahkan beban antara komponen dan jentera yang berbeza.
• Penjanaan koordinat, penyimpanan, dan memuatkan.

Sistem Perlindungan

Adakah anda mempunyai litar pintas? Kadang-kadang, beban yang tidak betul atau ketidakupayaan untuk mengendalikan beban yang diperlukan boleh membawa kepada isu litar.

Sistem Perlindungan ada untuk melakukan tugas berikut.

• Ia mengesan kerosakan dalam sistem dan menyediakan pengurusan yang lebih baik.
• Matikan sistem semasa kegagalan mesin.
• Mengendalikan kegagalan kritikal dengan mengasingkan komponen.

Pengurusan Beban Kritikal

Setiap kali anda mendapat kecemasan, sistem pengurusan beban kritikal berfungsi di barisan hadapan untuk menguruskan bekalan elektrik. Contohnya:

• Ia mengesan dan memantau sistem dengan beban keseluruhan.
• Periksa peralatan kritikal yang perlu anda kuasai.
• Membekalkan kuasa kepada alatan kritikal hanya semasa kecemasan.
• Membekalkan kuasa kepada alat yang kurang penting apabila tiada gangguan.

Bagaimana Sistem Kuasa Berdaya Tahan Berfungsi?

Berdasarkan komponen sistem kuasa yang berbeza, berikut ialah panduan langkah demi langkah untuk memahami cara pengeluaran tenaga, penularan, dan penggunaan berlaku.

Langkah 1: Operasi Biasa

Dalam keadaan biasa, sumber tenaga utama ialah sistem tenaga suria/angin. Mekanisme kerja adalah seperti berikut:

• Pada waktu siang, kuasa suria dihasilkan dan disalurkan kepada perkakas selepas penukaran.
• Bateri menyimpan tenaga.
• Semasa hari mendung atau gangguan, grid membekalkan kuasa.
• Penjana kekal dalam mod siap sedia sehingga ia diperlukan.

Langkah 2: Gangguan Berlaku

Atas apa jua keadaan, gangguan berlaku dalam sistem.

• Grid Utiliti pergi ke luar talian.
• Sistem Perlindungan bertindak dalam gangguan.

Langkah 3: Respon Segera

Sambutan pertama datang daripada bateri.

Here are the batteries.

• If your batteries are full, they instantly supply the energy to your devices.
• Critical devices are kept on while shutting down unnecessary or secondary importance devices.
• Automatic transfer switches work to operate and streamline the energy source transmission.

Ingat, during daytime or sunlight, solar power is still the primary source to feed the power to the system. When both grid and solar outages occur, batteries operate in such conditions.

Langkah 4: Extended Operations

Batteries are ideal only for a few hours of power outage. Contohnya, an outage of 4-6 hours can discharge the batteries depending on their power.

For extended operations, the power system works differently.

• Generators come into action. They consume fuel and provide energy to all your devices. Namun begitu, if you want to shed unnecessary devices, anda sepatutnya.
• Solar/wind power systems should supply energy during the daytime or as conditions are feasible.

Langkah 5: Recovery

When the grid power returns, the normal operating system resumes as follows.

• Grid takes control, and the main focus is on the renewable energy sources and the utility grid supplies.
• The system synchronizes and shifts from emergency mode to normal operating conditions.
• Generators shut down.

Types of Threats Against Which Resilient Power Systems Work
