MDMS
It provides meter reading status information for all areas using GIS. Based on the metering data, it shows the consumption patterns and status information of all customers in the service area, enabling the overall power status analysis.
Main Features of MDMS
The high-level conceptual functions of MDMS are divided into four areas: ‘data reception’, ‘data supply and delivery’, ‘data management’, and ‘data storage’. General detailed functions are defined as follows.
| Key Features | Description | |
|---|---|---|
| Data reception | Direct reception and loading of meter reading data | Data storage, management and maintenance |
| Receiving/loading other data from Advanced Metering Infrastructure (AMI) | ||
| Data supply and delivery | Command Management | Meter on off etc. |
| Provide Data to related systems | Scalability to support government smart meter goals. Receiving and managing information to support the relationship between the meter and third-party providers: MMD (MDMS Master Directory) | |
| Provide information to the users | Provide data by periodic or non-periodic requests | |
| Data Management | Validation and Editing of Meter Reading (VEE) | Verification, evaluation and correction of meter reading data. Provide audit function for data changes |
| Exception management, estimation of abnormal/missing meter reading | ||
| Event management | Ex) Recent surge/outage notification | |
| Meter reading profile analysis (Profiling) | ||
| Rate Factor Calculation | Provide rate data for consumers based on different rate structures including TOU, RTP and CPP. Tariff Table (Standard rate table by time) Update. | |
| Sum of meter readings | ||
| Meter history tracking | Provide end-to-end tracking of data usage within MDMS | |
| Security | Provide security for functions and data access management | |
| Provide additional functions | Analysis for prevention of missing sales, support of distribution plan, prepaid bill, etc. Meter location management, usage by household and year-over-year usage, solar power related functions | |
System Features
Meter Reading Status Information
- Based on data collected from all nodes (meter/modem/customer) installed in each region, it shows real-time power consumption status, patterns, and levels by region in charts and lists
- Able to analyze the power status supplied to each region (active power, reactive power, apparent power, power factor)
- Able to check the power demand level for each region by time (every 15 minutes)
- It shows meter reading status for each region
- It shows a list of unread meters for each region
Load Profile
- it shows the consumption patterns and status information of all customers in the service area in charts, enabling the overall power status analysis.
Metering Data
- It allows to individually check the billing information and consumption patterns of all customers in the service area by period, and compare and analyze the information of multiple selected customers.
