Manageable Networks and Electronic Meters; In electricity distribution enterprises; There are many issues in terms of business management, planning, and subscriber information management. Currently, efficiency is low due to lack of data on operation and electricity distribution and a waste of time in measurement, evaluation and interventions. With real-time data and a manageable network to address these problems, operating efficiencies can be increased, with a scalable and manageable system; Efficiency can be greatly increased by taking precautions and intervening in a timely way by both planning and technical loss and leakage electrical analyses. For the solution of all these problems, it is seen that the most appropriate structure is solved by smart network structure.
A smart grid is based on two foundations;
a-) Measurement and evaluation
b-) Managing and Routing.
Smart (Manageable) Networks and Subscriber Information Management Systems, a system that electricity distribution companies will need most in the execution of their services, are an integral part of each other and cannot be considered separate from the other for efficiency.
While there are many benefits of the Smart network system for each distribution zone, investment turnaround processes for each distribution zone of this Smart Network system to be established; the geographical structure of the region may be different due to reasons such as transportation facilities, leakage/loss rates.
Therefore, each deployment zone must configure the needs and analyses of the smart network setup before the decision stage. In addition, the demands and conditions of the institution, which has authority on behalf of the Public, must be evaluated in the analysis.
In the system when determining the needs; the weights of informatic information and operations applications should be distributed in a balanced way and transmission lines and data center should be used as efficiently as possible.
When designing a smart grid system;
- Network control and management,
- Load distribution and Demand forecast
- Fault Management,
- Transformer and/or Fider automation
- Geographic Information System (Inventory)
- Team and Material Management
- Counter Reading
- Open Cut
services must be integrated with each other, during network management and intervention,
reliable inspection must be applied in terms of property safety, otherwise it will be inevitable that there will be very sad consequences.
Manageable Networks and Electronic Meters – Network Management
Traditional Network Management Smart Network Management
|The network can only be examined physically and visually by observing the location to which it belongs, or upon request from 3rd persons.||All network information in the responsibility area is available to the user regardless of location in the digital environment, the user can access all information about the network as well as in real time.|
|Load distribution is only predictable. Technical loss calculation cannot be done because network information is not clearly known.||Voltage, current, power, frequency, cosØ values can be monitored in real time for each phase on the grid. Since network information is clearly known, technical losses can be clearly calculated and necessary measures can be taken.|
|Fault information on the network is generally transmitted to the business by 3rd party. Depending on the situation, the appropriate team is tasked with fixing the fault, the team reaching the scene intervenes in the fault or requests additional equipment, which means that electricity cannot be sold at that location during the period of time loss and failure.||The fault information that occurs in any location will reach the company spontaneously at the same time, the hardware information at the point of failure will be assigned because the hardware information is in the smart grid system, the team will reach the point of intervention with the necessary material accordingly, both the time will be used efficiently and the electricity sales process will continue again as the fault will be repaired in a short time.|
|Operations in transformer areas are carried out manually and on site in general.||Operations are managed through the center via remote access.|
|In general, there is no Geographic Information SystemEnvanter is calculated approximately.||There is a geographic information system connected to the network and as vibrant as the network, so asset management is realistic.|
|Because there is no complete inventory of equipment in the network, material and inventory management is based on informatics information from past times||Material, inventory and team management will be more efficient as network information is up to date in the system.|
|Energy buying points and counters for some high-consumption subscribers can be read remotely with GPRS or PSTN, but within each task zone, it is absolutely important to go to the counter point and read with hand terminals (gprs or gprs) to read subscriber counters of approximately 90% to 95% of the total number of subscribers, which in this application causes huge costs to the distribution company in total.||Thanks to OSOS (Automatic Meter Reading System), which can work integrated with the smart network, all subscribers connected to the network have the opportunity to read counter information remotely. In this case, transportation and personnel expenses will be saved, as well as hundreds of thousands of subscriber counters can be read during the day and the actual loss leakage rate analysis can be done.|
|To turn off and on customer energy, you need to go to the subscriber's counter site.||The opening and cutting of subscriber counters can be done remotely.|
Comparison of Traditional Power Grids and Smart Grids
From the field, all work done from the moment the data starts to be collected must be kept up to date otherwise it is inevitable that the data obtained shortly there will be no sense, if warehouse exit documents are linked to the work order in order to keep the data up to date, material management and team management and network information remain up to date and multiple scalable results are obtained through one process, as well as a serious infrastructure for the entire project, which is the main objective.
During the selection and configuration of the system, adequate alternative nutritional opportunities should be provided, especially considering the possibility that all active devices to be used in automation will be without power.
It is important to choose a communication protocol that will provide two-way communication in bandwidth according to the desired speed by specifying the amount of data to be used in the application.
When selecting the application, an Intelligent Network project should be prepared in accordance with the requirements and operating logic of our Country in place of an existing SCADA (Supervisory Control And Data Acquisition). During the analysis period of this project, participation should be provided from all relevant units in the distribution company, fixed and parametric options should be fully parsed and frequent, frequently changing rates and applications should be updated more comfortably in the future.
