S3M-STMV: The Online measurement, monitoring & management system for LV transformer.

 S3M-STMV is an Online measurement, monitoring & management system for LV transformer. S3M-STMV is capable of replacing traditional operation & management method, it can reduce man power, enhancing safety for electrical assets, grid and workers. The S3M-STMV provide the comprehensive and accurate data for online measurement, monitoring and management.

Changing from Conventional to Smart Transformer

 The advantage of the S3M-STMV system is easy to deploy and install; furthermore, it can be integrated with any LV transformer to change the on-site measurement & management method to Online managing.

I. The target of STMV

1.1. System Compatibility

Compatible with all type of Transformers

 The S3M-STMV system is compatible with all type of Transformers that are available on the market. The system has fully monitoring function to manage a transformer (via measuring electrical parameter as well as the status of the auxiliary equipment on the transformer).

1.2. S3M-STMV system: toward the smart grid system in Vietnam

 The S3M-SGMV is a strong & useful tool for centralized management of LV transformer. Under the eyes of a substation manager, a centralize management tool will assist him to predict abnormal, faults as well as the state of the electrical assets. The prediction might greatly base on the real-time data that collected by the management system.

 For the operators, the prediction of faults and incidents will help them to make decision about maintenance time and the exact position that need inspection.

 Traditionally, most of substations (from MV to LV) is decentralize operated and managed, this leads to high cost of operation (due to large number of workers). Furthermore, the traditional management way is lack of awareness (about abnormal, incidents). With this type of management and operation, when a problem occur or an inspection is needed, it will take a lot of time for traveling between substations to handle the situation.

 Once the LV substations are equipped with S3M-STMV system, a network of LV transformer will be Online managed. The monitoring data is in real-time and the operator will be aware of the operation of many LV substations at the same time, this leads to the lower cost of operation and management.

I. S3M-STMV structure

II. S3M-STMV system with many transformers

 The aim of the S3M-STMV system is deploying a network for centralize management of LV transformer, the substation monitoring & measurement process can be performed remotely via S3M software. This is convenient in management and monitoring on a large scale, saving labor & operating cost.

 S3M-STMV is an Online management, monitoring and measurement for LV substation with many utilities that can meet all the needs for 3M (Measurement-Monitoring-Management). S3M-STMV solution have been deployed in many provinces and regions across the country, our solution is directly installed and exploited by EVN on the distribution grid in Ha Noi, Ben Tre, Quang Nam, Bac Ninh, Bac Giang and HCM city.

The S3M-STMV system is suitable for both LV grid in residential area and industrial area, factory infrastructure, this is a useful tool that can be integrated with the energy management system SEMS-L and provided a comprehensive management of the factory electrical system.

Data gathering device STMV

 Is a multifunction monitoring device for LV transformer.

Functions

The device is capable of collecting and processing multi-point data in real time, including:

– Electrical parameter (main, branch): U, I, Cos ϕ, P, Q, S, Et.

– Transformer oil temperature.

– Transformer LV terminal contact temperature.

– State of substation auxiliary equipment: Fault indicator, oil-level, gas relay, SF6 density.

– Power quality monitoring.

– OLTC device state

– Winding temperature, DGA, moisture in oil transformer, PD, BM

S3M software

 S3M-WS4.0 is a monitoring software which perform Online monitoring, management and early warning (by collecting data from STMV device), this is a management software that is designed and developed by SES with many features:

– Visual interface and simple to use with tables and charts. The data is organized and displayed logically.

– Capable of accessing, exporting and displaying unlimited data ((by day, month, year and years).

– STMV devices are displayed and managed on GIS digital map.

– User authorization function.

– Alarms and warning are displayed in the main screen (include operational & device status warning)
