SurvalentONE DMS

SurvalentONE DMS (Distribution Management System) là giải pháp phần mềm quản lý lưới điện phân phối với các chức năng nâng cao, hỗ trợ người vận hành đưa ra những quyết định linh hoạt, nhanh chóng và chính xác. Phần mềm được xây dựng tích hợp trên cùng nền tảng SurvalentONE ADMS – SCADA, thừa hưởng đầy đủ các tính năng mà hệ thống SCADA sở hữu. Đây là cơ sở để triển khai tự động hóa lưới điện thông minh theo từng giai đoạn và điều kiện có sẵn của hệ thống.

By applying DMS functions, users will receive both immediate and long-term benefits:

• Enhance the ability to monitor grid operational status and propose accurate real-time decisions.
• Automate the distribution grid.
• Improve power supply reliability indices such as SAIFI, SAIDI, CMI, etc.
• Increase revenue by reducing power outage duration.
• Ability to commit to power supply performance for medium and large industrial customers.

Key highlights of SurvalentONE – DMS

SurvalentONE DMS offers a diverse range of functional options tailored to the needs and current system status of the customer:

Phase 1: DMS functions that do not require a network model/grid topology

• Switch Orders: Create control/restoration commands for devices.
• Power Factor Control (PFC): Control the power factor.
• Dynamic Voltage Regulation (DVR): Dynamic voltage regulation.
• Voltage Reduction (VR): Voltage reduction.
• Load Curtailment (LC): Load shedding.
• Rotational Load Shedding (RLS): Rotational load shedding.
• Short-term Load Forecasting (STLF): Load forecasting.
• Load Estimation (LE): Load Estimation.

Phase 2: DMS functions requiring network connectivity/topology

• Fault Location, Isolation, and Service Restoration (FLISR)
• Loss of Voltage (LOV)
• Protection Settings Manager (PSM)
• Distribution Contingency Analysis (DCA)

Phase 3: DMS functions requiring network model and connectivity

• Distribution Power Flow (DPF)/Distribution State Estimation (DSE)
• FLISR calculates load transfer based on DPF.
• Short Circuit Analysis
• Fault Location
• Volt/VAR Optimization (VVO)
• Optimal Feeder Reconfiguration (OFR)

FLISR: Fault Location, Isolation, and Service Restoration

• The system utilizes a fault location algorithm by combining telemetry data from field devices with the network model to rapidly identify and isolate the faulted area. Following isolation, FLISR automatically executes switching of tie devices to restore power to the maximum number of customers possible from adjacent sources, typically completing the process in under 30 seconds.
• Implementing FLISR helps utilities transform sustained outages into momentary interruptions, thereby enhancing power supply reliability and improving customer satisfaction.
• FLISR operates in three modes: Manual, Semi-Auto, and Auto, with flexible switching between load transfer calculation methods using kVA, protection device data, or Power Flow.

MP CO was the first company in Vietnam to successfully implement an automated SCADA solution—FLISR (Fault Location, Isolation, and Service Restoration)—for the 22kV power grids in Ho Chi Minh City and Da Nang (in 2017), operating in fully automatic mode.
