3. Fitur utama

● SVG dirancang oleh konsep komponen dan dapat membuat kompensasi untuk beban kapasitif dan induktif, dengan demikian mendapatkan efek kompensasi dengan tingkat PF 0.99 dan menghindari kompensasi berlebihan dan kurang kompensasi

● Waktu respons lengkap SVG kurang dari 10 MS dan waktu respons dinamis kurang dari 50 μs, Membuat SVG Pilihan Teratas untuk Lingkungan yang Mengubah Cepat.

● Kapasitor yang dilengkapi dengan SVG tidak memerlukan pemasangan bank filter; Oleh karena itu amplifikasi resonansi tidak akan terjadi. Selain itu, Sebagai perangkat kompensasi aktif dan perangkat sumber saat ini yang mengadopsi komponen cut-off seperti IGBT, SVG melarang resistensi dari perspektif mekanisme, secara signifikan meningkatkan kelengkapan.

● SVG dapat terus menyesuaikan daya reaktif secara dinamis dan dua arah (-1 ke +1); artinya, SVG dapat menghasilkan daya reaktif secara konstan baik di kedua kondisi kerja induktif yang dinilai dan dinilai dan dapat membuat kompensasi konstan dalam kisaran luas jika dikombinasikan dengan kapasitor tetap.

● SVG tidak memerlukan kapasitor atau reaktor berkapasitas besar untuk berfungsi sebagai elemen penyimpanan energi, dan area yang ditempati hanya setengah dari yang ditempati oleh jenis lain dari rakitan kompensasi dinamis dengan kapasitas yang sama, atau bahkan area yang lebih kecil. Lebih-lebih lagi, SVG mengadopsi desain modular dan instalasi tipe kabinet, yang hanya menuntut beberapa upaya dalam desain dan pemasangan teknik.

● SVG dirancang dengan sirkuit kompensasi aktif; Karena itu, Tegangan grid memiliki sedikit pengaruh pada kapasitas kompensasi. Output arus reaktif cocok dengan kondisi kerja bahkan ketika tegangan jaringan listrik rendah.

● SVG memiliki kehilangan daya yang rendah dan membutuhkan sedikit perawatan, Jadi peluang tegangan berlebihan resonansi cukup rendah. Kehidupan layanan berlangsung selama lebih dari sepuluh tahun (dengan MTBF lebih lama dari 100,000 jam).

● Efisiensi tinggi >97%

8. FAQ Tentang SVG Static Var Generator

Q1: What is a Static Var Generator (SVG)?

Generator var statis (SVG) is a power quality device for dynamic reactive power compensation. It helps stabilize voltage levels and improve power factor by injecting or absorbing reactive power as needed. Unlike traditional capacitor banks, SVG provides real-time compensation and works effectively under varying load conditions.

 

Q2: How do you select a Static Var Generator?

When choosing an SVG, consider the following factors:

-Reactive power demand: Determine the required kVAR rating based on the power system’s reactive power needs.

-Load type: Suitable for industries with fluctuating reactive power demands, such as welding, pusat data, and steel plants.

-Response time: Look for fast response times (typically <5MS) for handling dynamic loads.

-System voltage and capacity: Ensure compatibility with the existing electrical infrastructure.

-Installation environment: Consider indoor or outdoor installations and environmental factors like temperature and humidity.

 

Q3: What is the difference between a Static Var Generator and a Capacitor Bank?

SVG: Uses advanced power electronics (IGBT-based technology) for real-time reactive power compensation, providing continuous, stepless control.

Capacitor Bank: Uses fixed or switched capacitors to compensate for reactive power in discrete steps, which may lead to overcompensation or undercompensation.

 

Q4: What is the difference between an SVG (Generator var statis) and an AHF (Filter harmonik aktif)?

Feature	SVG (Generator var statis)	Ahf (Filter harmonik aktif)
Primary Function	Kompensasi Daya Reaktif (power factor correction)	Harmonic compensation & power factor correction
Key Benefit	Voltage stability, improved power factor	Reduction of harmonic distortion
Best for	Power factor correction & voltage stability	Harmonic-rich environments (VFDS, UPS, nonlinear loads)
Technology	IGBT-based real-time compensation	IGBT-based real-time harmonic filtering
Response Speed	<5MS	<1MS
Effect on Harmonics	Does not eliminate harmonics	Actively cancels harmonics

SVG is ideal for voltage stability and reactive power control.

AHF is better for harmonic-rich environments and power quality improvement.

For complete power quality solutions, SVG and AHF can be used together in complex electrical systems.

 

Q5: Is SVG suitable for all types of loads?

SVG is ideal for dynamic loads that require reactive power compensation and power factor correction, including:

Welding equipment (arc welding machines, resistance welding machines)

Elevators, cranes (rapidly changing loads)

Renewable energy systems (wind power, solar PV)

Industrial applications (steel, chemical, cement industries)

Data centers, rumah sakit, airports (high power quality requirements)
However, SVG has limited effects on pure resistive loads (e.g., electric heaters).

 

Q6: Will SVG conflict with AHF (Filter harmonik aktif)?

TIDAK, SVG and AHF can work together to improve overall power quality:

SVG focuses on reactive power compensation and power factor improvement.

AHF eliminates harmonics and reduces Total Harmonic Distortion (Thd).

Using both in combination is ideal for environments with nonlinear loads such as VFDs, UPS, and electric arc furnaces.
