Intelligent Management Of Electrical Systems In Industries Pdf
An energy department or company is in charge of local energy production and of the distribution network. It providesopportunity to identify exact fault location and more organised restoration activity. The discussion will address various components, technologies and principles for the working models. In their efforts to approach thisdesired state of network operations, utilities are keeping tab on a bigger concept, i.
The Flexible Electric Architecture and the Open Communications Architecture synergistically empower each other to create the distribution system of the future. Reliable forecasting assumes use of methods which can utilize production plans in some time distance which also can have a large difference with each other and include inaccurate information. The capabilities can be used to verify exact location and extent of outages as well as optimized mobilization ofmobile field force to assist in power restoration. Predictive condition monitoring, reliability calculations, and protection relay coordination to prevent disturbances in advance are more important.
Description of the system environment A big industrial plant differs from public distribution company by organizatory structure and by system environment. The distribution system of the future will be more versatile and will be multifunctional. The system should provide outage analysis on geographic landscape and should be able to support applications like realtime network analysis and remote switching. Load models can be determined by making enough measurements in different known process conditions. In industrial plants the load modeling should be based mainly on the process.
The losses of production caused by the disturbances and the inputs into the investments of the systems including maintenance and operational arrangements join here. However, the industrialplants vary from each other quite much, which means that load models determined in one plant may not be able to used as such in other one. ConclusionThe intelligent electrical system provides thee utilities real-time information of thee network and the energy supply.
Intelligent electrical system
Prototype versions were tested in a real environment from the very beginning. Each of these is made more valuable by its interaction with the other. The network model includes the real-time topology and network calculation results in the prevailing switching and load conditions.
The distribution network is modeled as dynamic objects which are generated based on the network data read from the network database. In case of catastrophic outages, utility can assess which customer segments arerectified and which are not, and improve customer awareness by publishing appropriate data for viewing. Usually there are only few measurement points in the network.
This mainly supports documentation of network data planning operation and. Normally, because of the reliability reasons, vital parts of distribution network control is independent on the process automation. The databases contain information of material flow, energy flow and control data of production machines. Similar information of electricity network components is supported by network database. An essential need is the load modeling which differs considerable from the public distribution.
To calculate inverse of matrix with conventional methods is now too laborious and therefore discarded. Different network operation tasks call for different kinds of problem solving methods. In a quantitative analysis indicators describing the capabilities of the system are calculated.
The fault location system has been one reason for the reduced outage times of customers i. Now customize the name of a clipboard to store your clips. You just clipped your first slide! The operators had considerable heuristic knowledge to be utilized, too.

Further the industrial processes will be developed and so the load models must be able to adapt in varied situation. The infrastructures of different industry plants vary more from each other as compared to the public electricity distribution, which is more homogeneous domain. The network model includes the real-time state of the network e.
Table below provides acomparison of the benefits of implementing Intelligent Electrical System vis-a-vis Smart Grid. This paper discusses the requirements of intelligent methods in the new domain, introduces the system environment and presents initial results gained in the research work. Various modules can operate interactively with each other through the network model, which works as a blackboard e. With a qualitative analysis the possible states of the system and reasons which lead to these are determined with non-numerical methods. Maintenance databases include technical specifications and condition data of production machine components.
Intelligent Management of Electrical Systems in Industries
Caused by the features of industrial networks the importance of the distribution management functions are different as in public electricity networks. Production programs are stored in the databases of administrative systems. High availability power systems Redundancy options-seminar report. Intelligent Management Of Electrical Systems in Industries - Network, process and motor measurements are available for the system. Most of the faults have been located with an accuracy of some hundred meters, nptel c programming pdf while the distance of a fault from the feeding point has been from a few to tens of kilometers.
Intelligent Management Of Electrical Systems in Industries On-line condition monitoring of components of electricity distribution network is not commonly used. What is an Intelligent Electrical System? Intelligent electrical system. The paper discusses on the requirements of new applications and methods that can be used to solve problems in the areas of distribution management and condition monitoring of industrial networks.
The load forecasting of the network feeding some process bases on the known behavior of the process, earlier measured values and the planned production. Visibility Others can see my Clipboard. Electric motors are often considered to be very reliable, which means that investment not economically justified. In fact, the calculation can be done simply by inverting a matrix. These units have the responsibility of production and maintenance.
Popular in Science General. The aim of a real application in the technical sense was thus been achieved. Utilities need to orchestrate business data by establishing an integration framework and building a communication network.
Switching plans operational instructions can furthermore be stored in databases. The loading information is read from the Access database including the load models for different situations. Classic Newton-Raphson iteration is considered be the most competent method for solving load flow equations, and was selected as the solver. Very promising results has been gained, for example, in decreasing outage times of customers. The failure modes, effects and.
The essential need for the load models is that they form a basis for the load-flow calculations. Business Integration FrameworkCollection of the necessary bytes of information from diverse sources will act as the backbone for the entire system architecture.
Thus the intelligent management of electricity distribution including, for example, preventive condition monitoring and on-line reliability analysis has a great importance. Advanced capabilities such as networkmonitoring, contingency analysis, fault handling can go far in giving utilities the power to be successful. The prototyping meant the iteration loop of knowledge acquisition, modeling, implementation, and testing. In the domain of public electricity distribution hourly load curves have been determined for each customer group to be used in load-flow calculation and load forecasting. Protection relays include some functions for condition monitoring such as self diagnostics of relay and counter of operations.
Clipping is a handy way to collect important slides you want to go back to later. Successfully reported this slideshow. Monitoring usually covers electric motors that are connected to the monitored processes. The calculations make it possible to simulate faults, to plan. Stephen Hadden, Shannon Messer.
