As the 750kV substation has the characteristics like incomplete information, uncertain diagnosis result and dual protection configuration, a fault diagnosis method of substation with redundant protection configuration based on rough sets and grey relational analysis is proposed. In this method, the diagnosis decision table which takes advantage of information about wave-recording devices and tw...

Electricity substations and their associated transformers are necessary for community power needs. In NSW these substations are often located in rural areas where background noise is low. Noise ‘hum’ from the transformers can be an issue for residents located nearby to the substation, and the tonal and low-frequency nature of the noise can add to the annoyance. The NSW Industrial Noise Policy a...

The study verifies the potential application of renewable energy sources in a district heating substation. Different operating configurations heat have been analysed, including solar collectors, PV panels and air source pump. Concepts regulating water parameters substation analysed. Moreover, impact storage tank has calculated using genetic algorithm to find optimal conditions analysis is based...

Abstract A miniaturized analog load-checking relay protection test device is developed in this paper, which a high-precision wireless phase volt-ampere configured. This device, characterized by intelligence and ease of operation, realizes the detection transformation ratio, polarity, phase, etc. secondary wiring transformer smart substation merging unit conventional substation. It meets testing...

The Faculty of Teacher Training and Education is one the Faculties that has most buildings in Tadulako University, which course requires large capacity electrical equipment facilities also electric power as well. To provide optimal services so lecture, practicum other activities are not disrupted due to problems.
 Electricity problems at currently caused by excessive loading adjusted trans...

Introduction Over the past decade, the traditional corporate network has come under siege from a proliferation of viruses and malicious intruders. As a result, numerous network security technologies, methodologies, and policies have been developed to secure the business system. In comparison, process control systems, with their reliance on proprietary networks and hardware, have long been consi...

Nowadays, electrical energy is of vital importance in our lives, every country needs this resource to develop its economy, factories, businesses, and homes are the basis economic structure a country. In city Newcastle as other cities constant development growing day by terms industries, these elements ones that consume all electricity produced Newcastle. Although Australia has strategically loc...

This article describes the need of using Protocol Engineering techniques to study current telecontrol protocols and this way improve their performances by setting them up or changing for others, such as standardised ones (testing their implementations).
