A Real-Time Design Model for Monitoring Electrical Power Transformers from Substations to the Consumers
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 8
Abstract
Widely used in industry for Supervisory Control and Data Acquisition of industrial processes, SCADA systems are now also penetrating the experimental physics laboratories for the controls of ancillary systems such as cooling, ventilation, power distribution, etc. SCADA systems have made substantial progress over the recent years in terms of functionality, scalability, performance and openness such that they are an alternative to in house development even for very demanding and complex control systems as those of engineering experimental research. This research is focused on bringing out vividly the design model and its major components and controls of the electrical power transformer monitoring. It addresses the application of a distributed management system geared towards attaining smart grid functionality. Moreover the research seeks to describe the key electrical equipment and also the operation of the various electrical power transmission and distribution systems. It also underscores the impacts of SCADA application on grid design, with a view to achieving reliability, effective performance, and operation. It also describes the security challenges associated with the deployment of this technology in power systems transmission, distribution and control. The use Supervisory Control and Data Acquisition (SCADA) system (LabView 2013) to monitor Power transformer parameters remotely as applied to other industrial applications has been brought out in the discussion. Remote monitoring of power transformers with the help of SCADA system is achievable because of the capability of LabView 2013 to transmit data over internet. This therefore means that every personnel with access privileges can log in to the MTUs - master server anywhere he or she is. This has been discussed a screen printout of the web page a simulated example has been showed. Security concerns associated with communication networks for the Industrial Control Systems (ICS) have been discussed comprehensively. The ultimate objective is to come up with a model of remotely controlling transformers and hence network connectivity is the backbone of data transmission. Issues to do with in-depth defense strategy for such networks have therefore been looked at in detail. For efficient operation of a power transformer some key parameters should be kept within the acceptable levels. The quantities to be measured and monitored include temperature, a.c phasor components (voltage, frequencies and currents), loading and bushing condition. Temperature and voltage inputs and outputs have been solely selected in the design model because of the complexity of the system that would need to monitor other parameters. The major signals obtained from the remote locations include signaling alarms, indication of status conditions, time varying values, and total metered values. However, an extensive range of information can be gathered using the available signal types.
