The Benefits of Having Improved Reliability of Speed Distribution and Automated Networks

In a private network setting, there are no unauthorized traffic that can travel around the network. With this in mind, this can totally eliminate the risk of having unsolicited traffic that can come from external sources. All of the data that is sent to and from several devices is now configured to a set private network that is segregated and separated from other sources of traffic. However, in such a private network like this, the customer can get a pool of set machine to machine (MSM) data plans that is designed for the DA application.

In conjunction with these type of applications, different cellular modems and routers are now designed through the solution given by the supplier and now being used for the IPsec tunnels, firewalls, and special filtering to have different sets of data to be securely transmitted between data and field devices. The MSM data plans for different DA solutions are designed to have a well defined and tested ways to support various types of applications.

For example, a manufacturer’s system may opt to use the small Ethernet IEC 61850 Generic Object Oriented Substation Event (GOOSE) type of messages to be able to communicate and transfer the information from peer to peer between the pole-mounted field controller devise or servers. This happens on the cost-efficient machine to machine data plans that are build to support different applications such as DTT, FLISR, and ATS that happens in different private cellular networks.

Several DA systems heavily depend on the available communication lines to be able to perform as it was originally designed for. As a failsafe, once the system successfully detects that a certain model was unusually disconnected from its cellular network, the system will successfully automatically give notification to the operator when the link is down. This service notification will give support to the customers to be able to have a better maintenance in their communication system lines that will variably support OT applications.

For the progressive electrical utility, a good combination of the cellular communications and the recent approaches to the new distribution systems feeder protection and automation stars gathering improved system reliability. On the other hand, the traditional approach for this system comprises of two distinctly different system functions: protection first and then automation.

The recent protection system should disconnect from the faulty networks that coordinates the overcurrent tripping that has auto-reclosing actions. Once the automated system successfully locates the faulty segment from the feeder, it isolates the faulted segments and it now executes the automatic closure of the field then it transfers switch to be able to provide the alternate energy from a different power source to functioning feeder segments. This is usually described as self-healing.

The recent approach disregards the complexity of adaptation of different coordinated overcurrent settings on several devices once the topology undergoes change. It then will be executed by the automated system. For this to happen, the automated and protection sytems should be closely monitored and coordinated in different actions – both in protection and automation. This helps to have an effective operation and protection for these types of automation actions to be executed successfully.
