• Risk Assessment of Power Systems with PSS™E

  Siemens

  Risk assessment of power systems can be performed using a deterministic or probabilistic approach. The traditional deterministic methods for transmission planning and power system security assessment in realtime for system operations have been found to be inadequate in the new deregulated environment as power systems present a probabilistic behavior to some extent, such as random failures of equipment, load growth forecast uncertainties, energy import and export transactions on the volatile market, etc. Use of the probabilistic reliability method complimentary to the deterministic method is getting more and more attention in both system planning and operation. This increasingly requires quantification of benefits as a result of increased reliability or decreased risk. The newly implemented reliability features in Siemens PTI’s PSS™E employ both deterministic and probabilistic reliability methods that can be used for risk assessment of power systems in a deregulated, competitive power market.

• Application Guidelines for Power Swing Detection on Transmission Systems

• New Intelligent Electronic Devices and Systems Change the Structure of Power Distribution Industry

  Siemens

  With the introduction of new Intelligent Electronic Devices (IEDs), classical disciplines in utilities like protection, control, non-revenue metering, power quality analysis, disturbance recording and automation will come under one responsibility. The IEDs with very high functionality will lead to significant cost savings and offer new problem solving capabilities. With these changes, utility personnel will need extensive training on the new practices, and a close partnership between vendors and utility customers will be necessary.

• Protection, Metering, Monitoring and Control of Medium Voltage Power Systems

  Siemens

  Traditional practices for industrial and commercial medium voltage power systems to provide protection, metering, monitoring, control, power quality analysis, disturbance recording and automation have changed. The new multifunction numerical protection relays using the processing power of the present generation of microprocessors, have very high functionality. Many functions can be integrated into one device, allowing new power system problem solving capabilities while permitting significant cost savings as compared with discrete protective relays, instruments, meters, recorders and transducers of the past. This paper describes the vast capabilities and recent enhancements of these devices, which will be called Intelligent Electronic Devices (IEDs) in this paper. Included are anecdotes obtained from an installation on a large industrial power system.
