10 kV Distribution Transformer ug Microgrid Collaborative Operation Product Solution

1. Hamong

1.1 Kasinatang Adaptasyon sa Bidireksiyonal na Pagtumaw ng Kuryente

• Pagbabago sa Voltaje & Panganib sa Overload

Ang bidireksiyonal na pagtumaw ng kuryente ay nagpapalubha sa hindi pagkakataon ng voltaje at overload sa mga kagamitan, na nagpapanganib sa mga transformer at integridad ng grid. Kinakailangan ang enhanced adaptive design.

• Limitasyon sa Unidireksiyonal na Design

Ang mga konbensyon na 10 kV distribution transformers, na disenyo para sa unidireksiyonal na pagtumaw ng kuryente, ay may hirap na acommodate ang integrasyon ng distributed generation sa microgrids.

• Kalidad ng Kuryente & Tagal ng Kagamitan

Ang optimized transformer designs ay nagpapabuti ng adaptasyon sa bidireksiyonal na pagtumaw ng kuryente, na nag-aasikaso ng matatag na suplay ng kuryente at pahaba ng tagal ng kagamitan.

1.2 Hamong sa Kontrol ng Kalidad ng Kuryente

• Intermittency & Harmonic Distortion

Ang microgrids ay naghaharap sa intermittent na renewable generation at harmonic pollution mula sa power electronics, na nagpapahirap sa stability ng voltage/frequency.

• Tumaas na Losses & Degradation ng Insulation

Ang komplikadong environment ng kuryente ay nagpapabilis sa losses ng transformer at localized overheating, na nagdudulot ng aging ng insulation at panganib sa fault.

• Pagsusulong ng Operational Safety

Ang advanced power quality mitigation ay nagbawas ng losses at faults ng transformer, na nag-aasikaso ng mas ligtas na operasyon ng microgrid.

1.3 Mahina na Komunikasyon & Koordinasyon ng Control

• Limitasyon sa Real-Time Data Exchange

Ang umiiral na 10 kV transformers ay walang robust communication interfaces para sa microgrid energy management system (EMS) integration.

• Barriers sa Scheduling & Optimization

Ang limitadong interoperability ay nagpapahirap sa flexible dispatch at optimal microgrid operation.

• Necessity ng Intelligent Upgrade

Ang smart transformer upgrades na may IoT-enabled communication protocols (e.g., IEC 61850) ay mahalaga para sa grid-edge controllability.

1.4 Inadequate Protection Configurations

• Protection Coordination Challenges

Ang tradisyunal na protection schemes ay hindi nakakatugon sa pagbabago sa direksyon ng fault current dahil sa distributed energy resources (DERs).

• False Trip Risks

Ang bidireksiyonal na pagtumaw ng kuryente ay nagpapahirap sa overcurrent/earth fault protection coordination, na nagpapataas ng misoperation risks.

• Adaptive Protection Solutions

Ang directional overcurrent relays at synchrophasor-based algorithms ay kinakailangan para sa fault isolation sa hybrid grids.
