[White Paper] Europe’s Window of Opportunity for Terminal OperatorsSchneider Electric
As Europe is going through an unprecedented financial and economic crisis,
the oil and gas industry continues to face an uncertain business environment.
Another recession could lead to reduced demand and further increase the
pressure on margins in downstream operations. This has suppliers and buyers
looking to exploit any operational efficiency they can.
Terminal operators play a critical role in helping suppliers and buyers achieve
those efficiencies, and can benefit their own operations while doing so. To gain
a competitive edge, terminal operators need to be mindful of the big trends
in the industry and make sure that their Terminal Automation System (TAS)
is capable of supporting state-of-the-art supply management systems that
suppliers intend to use in order to maximize their efficiency. And for most TAS,
a simple configuration change is all it takes to achieve this.

Data centers today lack a formal system for classifying infrastructure management tools. As a result, confusion exists regarding which management systems are necessary and which are optional for secure and
efficient data center operation. This paper divides the realm of data center management tools into four distinct subsets and compares the primary and secondary functions of key subsystems within these subsets. With a classification system in place, data center professionals can begin to determine which physical infrastructure management tools they need – and don’t need – to operate their data centers.
ANALYSIS OF NETWORK PERFORMANCE MANAGEMENT DASHBOARDIAEME Publication
Analysis of performance availability is very important to help improve network
performance. This is due to developing services to be used by customers. In performance
availability it is known that there are many problems that occur in each event in the
field. In achieving the optimal level in carrying out the implementation and support
processes of the performance management dashboard, an analysis is needed to develop
management and control in the networking division with the aim of generating
utilization in the implementation and support processes to align with the business needs
of PT ABC. The existing reference model is a reference model that refers to the
functional area of FCAPS. The FCAPS model consists of five functional areas,
including fault management, configuration management, accounting management,
performance management, and security management. In general, companies have
implemented FCAPS on failure issues and configurations (fault and configuration).
Security / security has relied on other tools that are not integrated in the FCAPS model
as a whole. The basic principle is, even though there are five elements from FCAPS,
one element can influence the success of other elements.

The growing trend for protection and control and substation automation is the digital substation. This is generally understood to mean fully implementing process bus. While adopting process bus provides great value, it is only a stepping stone. The long-term goal must be to move away from the current single-purpose, hardware-based protection and automation systems and replace them with a software-defined control system running virtual services: a digitally enabled substation.
A digitally enabled substation is necessary to enable substation systems to adapt to the new realities of changing distributed energy resources impacting feeder power flow, voltage, and protection functions, and the changing operating requirements brought on by widely distributed, inverter-based resources. Wind, solar, battery storage, and EVs maybe be connected anywhere to the grid, and by different owners often concentrated in areas negatively impacting the traditional grid. Operators and control functions must plan for and adapt quickly to changes in available resources and load flows. Utilities, systems owners and a host of new DER stakeholders will need to be able to roll out new applications and access an increasing amount of grid data to optimize their investments. Old schemes will need to be adapted quickly and reliably throughout the entire system.
A data center infrastructure management (DCIM) system collects and manages information about a data center's assets, resource use, and operational status.

breaker A at receiving station trips and all substations on the
ring up to NOP1 (A-B-C) looses power. Then the field crews
are physically sent to a substation (say B) to open the switch
or isolator. This might take anywhere between 10 to 30
minutes in a congested city like Mumbai. A ‘test charge’ is
then taken from control centre by closing the breaker A at the
receiving station. If it holds, the fault is beyond substation B.
Between B and NOP, again by trial-and-error, the faulty
section is identified (DE). Total fault isolation time is
approximately 40 to 60 minutes.
