United States agencies involved with national security are concerned about the vulnerability of the North American electric power grid to electronic intrusions, commonly known as cyber attacks. Several studies have identified changing socio-economic conditions that increase the probability of an electronic, computer-based attack being launched against a utility or substation, causing regional a...

This paper presents the concept of the generalized power source in an active distribution network. After the energy storage system (ESS), distributed generators (DG), and demand-side controllable load are connected to the active distribution network, part of the system load can be undertaken by these ESS, DG, and controllable load instead of relying on the capacity of the substation, which grea...

Most substations today contain a large number of Intelligent Electronic Devices (IEDs), each of which captures and stores locally measured analogue signals, and monitors the operating status of plant items. A key issue for substation data analysis is the adequacy of our knowledge available to describe certain concepts of power system states. It may happen sometimes that these concepts cannot be...

As the latest standard that is quickly gaining popularity in power substation automation, IEC 61850 offers self-descriptive object data models, standardized configurability with Substation Configuration Language (SCL), the promise of interoperations among intelligent electronic devices (IEDs) from different manufacturers, and lower integration installation costs. The IEC 61850 standard initiall...

The PMU has been found to carry great deal of value for applications in the wide area monitoringof power systems. Historically, deployment of these devices has been limited by the prohibitivecost of the device itself. Therefore, the objective of the conventional optimal PMU placementproblem is to find the minimum number devices, which if carefully placed throughout thenetwork, e...

With the government's emphasis on environmental issues of power transmission and transformation project, noise pollution has become a prominent problem now. The noise from the working transformer, reactor, and other electrical equipment in the substation will bring negative effect to the ambient environment. This paper focuses on using acoustic software for the simulation and calculation method...

With ongoing efforts to make the power grid smarter, there is a large emphasis on the automation and data analytics. Substation automation is a key enabling technology for online monitoring, diagnosis and prediction for the health condition of the substation assets. Circuit breakers (CB) are one of the most vital components in a substation for tripping action required during the fault occurrenc...

Usually, distribution electricians are called upon to solve technical problems found in electrical substations. In this project, we apply problem-based learning to a training program for electricians, with the help of a virtual reality environment that simulates a real substation. Using this virtual substation, users may safely practice maneuvers with varying degrees of complexity. To improve t...

With the maturing of the Utility Communication Architecture (UCA), utilities are beginning to implement substation protection and control systems that are based on this technology. This paper describes such an implementation for the control of the Bateias 525kV substation on the COPEL power system in Brazil. In particular, the paper will describe the customer’s requirements and expectations wit...
