Ⅰ. Sektor Paggamit ng Kuryente sa Timog-Silangang Asya: Katayuan at Analisis ng Kagustuhan
- Kahinaan ng Grid at mga Hamon sa Pag-access sa Enerhiya
 
- Higit pa sa 35 milyong tao sa Timog-Silangang Asya ang wala pang access sa kuryente. Ang mga malalayong lugar ay nakadepende sa mga generator na diesel (halimbawa, ang Baryo Padua, Indonesia), na may hindi matatag na supply at mataas na gastos.
 
- Ang tropikal na klima ay nagdudulot ng mataas na pagkawala ng kuryente sa linya. Ang integrasyon ng mga sistema ng photovoltaic (PV) at electric vehicles (EVs) ay nagpapahaba ng mga isyu ng hindi pantay na tensyon sa grid ng distribusyon.
 
- Pangangailangan para sa Integrasyon ng Bagong Enerhiya
 
- Mabilis na paglago ng distributed PV (halimbawa, ang Tsina ay idinagdag 120 GW na distributed PV noong 2024), ngunit ang koneksyon sa grid ay nagdudulot ng pagbabago ng tensyon.
 
- Pagtaas ng mga proyekto ng imbakan ng enerhiya na off-grid (halimbawa, ang proyekto ng Jinko 10MWh), na nangangailangan ng teknolohiya ng pagsiguro ng tensyon upang matiyak ang kaligtasan ng mga aparato.
 
- Mga Boteng Infrastruktura
 
- Mataas na proporsyon ng mga lumang kagamitan ng kuryente (higit sa 50% sa US/Europe ay lumampas sa 20 taon), na nagbibigay ng urgenteng pangangailangan para sa epektibong solusyon ng pagsasabog.
 
II. Disenyo ng Teknikal na Solusyon ng SVR (Voltage Regulator)
(A) Core Architecture: Intelligent Adaptive SVR System
Nagsasama ng tradisyunal na step voltage regulation at digital control technology upang makamit ang multi-scenario voltage stabilization.
- Hardware Configuration
 
- Main Control Unit: Gumagamit ng dual-core DSP microcontrollers (halimbawa, TI Delfino series), na sumusuporta sa real-time voltage sampling at harmonic analysis.
 
- Power Module: Naglalaman ng IGBT/MOSFET switch banks, na sumusuporta ng ±10% voltage adjustment range kasama ang 16-tap selection (0.75V step increments).
 
- Cooling System: Liquid cooling na may kontrol sa temperatura (halimbawa, ang solusyon ng Jinko), na may battery cell temperature differential ≤ ±2.5°C.
 
- Software Algorithms
 
- Optimized LDC (Line Drop Compensation) Control: Nakakadetect ng three-phase imbalance sa pamamagitan ng IT (Load Tap Changer) switching data, at dinamikong nagsasadya ng mga target ng voltage regulation.
 
- AI Predictive Strategy: Nangangahulugan ng output ng PV at mga peak/valley ng EV charging batay sa historical load at weather data, na nagbabawas ng frequency ng tap-changer operation ng 30%.
 
(B) Pag-customize para sa Timog-Silangang Asya
- Environmental Adaptability
 
- IP65 protection rating, tolerance for high temperature (≤50°C), mataas na humidity (≤95% RH), at salt spray corrosion (coastal areas).
 
- Lightning protection design: Integrated MOV surge arrestors, withstands 10kA lightning current.
 
- Dual Mode Support (Off-grid / Grid-connected)
 
- Off-grid Mode: Black start capability (halimbawa, Jinko PCS), sumusuporta sa hybrid power supply ng diesel-PV-storage.
 
- Grid-connected Mode: Harmonic mitigation (THDi ≤3%), reduces interference from PV inverters and EV chargers.
 
- Cost Optimization
 
- Modular Design: Single cabinet supports 0.4kV~22kV voltage levels, reducing expansion costs by 40%.
 
- Localized Supply Chain: Partners with Chinese manufacturers (halimbawa, BTR) to establish facilities in Indonesia/Thailand, reducing equipment costs by 25%.
