3. 주요 기능

● The component concept designs SVG and can make compensation for both capacitive and inductive loads, 따라서 PF 수준으로 보상 효과를 얻는다 0.99 과잉 보상 및 보상을 피합니다

● SVG의 완전한 응답 시간은 10 MS, and the dynamic response time is less than 50 μs, 빠르게 변화하는 환경에서 SVG를 최고의 선택으로 만듭니다.

● SVG와 함께 제공되는 커패시터에는 필터 뱅크 설치가 필요하지 않습니다.; 그러므로, resonant amplification will not happen. 게다가, 활성 보상 장치 및 IGBT와 같은 컷오프 구성 요소를 채택하는 현재 소스 장치로, SVG wards off resistance from the perspective of the mechanism, 완전성을 크게 향상시킵니다.

● SVG (-1 에게 +1); 즉, SVG can output reactive power constantly in both rated capacitive and rated inductive working conditions, and it can make constant compensation in a wide range if combined with a fixed capacitor.

● SVG는 에너지 저장 요소 역할을하기 위해 대용량 커패시터 또는 원자로가 필요하지 않습니다., 그리고 그것이 차지하는 영역은 동일한 용량을 가진 다른 유형의 동적 보상 어셈블리가 차지하는 것의 절반에 불과합니다., 또는 더 작은 지역. 게다가, SVG는 모듈 식 디자인 및 캐비닛 유형 설치를 채택합니다, 엔지니어링 설계 및 설치에 몇 가지 노력이 필요합니다..

● SVG는 활성 보상 회로로 설계되었습니다; 그러므로, 그리드의 전압은 보상 용량에 거의 영향을 미치지 않습니다.. 반응성 전류의 출력은 전력망의 전압이 낮더라도 작업 조건과 일치합니다..

● SVG는 전력 손실이 낮고 유지 보수가 거의 필요하지 않습니다., so the chances of resonance overvoltage are pretty low. 서비스 수명은 10 년 이상 지속됩니다 (MTBF가 더 길다 100,000 시간).

● 고효율 >97%

5. Working Principle of a Static Var Generator (SVG)

정적 var 생성기, also known as a Static Var Compensator (SVC) or Active Power Factor Correction device, is an advanced electrical device used to improve power quality in electrical systems. It helps correct power factor, reduce reactive power, and balance voltage.

How Does It Work?

When electrical equipment like motors, 압축기, or welding machines run, they often draw reactive power (non-usable power). This causes a low power factor, which leads to:

-Wasted energy

-Higher electricity bills

-Overloaded cables and transformers

The Static Var Generator continuously monitors your power system in real time. It then injects or absorbs reactive power instantly, like a shock absorber for your electricity, to keep the power factor close to 1.0 (ideal).

What Happens Step-by-Step?

Measurement: The SVG measures voltage, 현재의, and power factor many times per second.

Calculation: It calculates how much reactive power is needed (positive or negative).

Injection: Using power electronics (like IGBTs), it injects or absorbs that exact amount of reactive power.

Correction: This keeps your power factor stable and your system efficient, automatically and in real time.

Benefits for You

Lower electricity bills (by avoiding penalties)

Better equipment life (due to stable voltage)

Reduced heat and losses in cables

Compliance with utility power factor requirements

In Summary, think of a Static Var Generator as a smart helper in your power system. It keeps your electricity “clean” and efficient by correcting imbalances, so you save money and protect your equipment.

6. Key Benefits of Using a Static Var Generator (SVG)

(1) Improved Power Factor

Maintains power factor close to 1.0, automatically.

Avoids penalties from utility companies for low power factor.

Ensures efficient use of electrical energy.

(2) Reduced Reactive Power Flow

Eliminates or greatly reduces the amount of reactive power in the system.

Frees up capacity in transformers and cables for real (active) 힘.

Less heat generation and energy loss in the system.

(3) Enhanced Equipment Performance

Stabilizes voltage, reducing stress on motors, drives, and sensitive equipment.

Increases the lifespan of electrical components by reducing wear and tear.

Minimizes nuisance tripping of breakers and protective devices.

(4) Real-Time, Dynamic Compensation

Responds in milliseconds, much faster than traditional capacitor banks or reactors.

Adapts instantly to changing loads—ideal for variable or heavy industrial equipment (예를 들어, 용접기, 크레인, 엘리베이터).

(5) Cost Savings

Lower electricity bills by improving power factor and reducing energy losses.

Delays or avoids the need for upgrading transformers or cables.

Helps in achieving compliance with grid codes and utility standards.

(6) 에너지 효율 & Sustainability
