presence of distributed generation (dg) in electric distribution systems provides an attractive new alternative in capacity expansion planning of these systems. in this paper a new model is developed for solving simultaneous placement of hv/mv substations and dg units as a static planning tool. this model aims to minimize fixed and variable costs of planning. constraints related to dgs, substat...

Smart substation primary equipment on-line monitoring technology is an important part of the realization of substation intelligentizes monitoring. In order to meet the requirements of smart substation on high-speed, efficient, steady on-line monitoring system, the sharing of online monitoring data of the power station and to improve interoperability of on-line monitoring device, the primary equ...

The paper discusses substation IED data integration and its importance for implementation of automated analysis solutions. Recorded data collected from various substation IEDs is stored into a substation data mart that utilizes standardized file formats and a database interface. The data mart provides a foundation for multiple uses of substation data. Utilities are faced with a challenge of how...

As it is well known, different Intelligent Electronic Devices (IEDs) may be utilized for collecting field data in any given substation. If substation automation systems are installed, data integration using a substation PC is a relatively easy task. What are the benefits of utilizing the substation data for various purposes remains the subject of a discussion in the industry. Protection and EMS...

Based on Multi-Agent (MA) technology and Artificial Immune (AI) theory, a novel substation fault diagnosis approach is proposed in the paper. The method firstly considers substation fault diagnosis a global complicated problem in uncertainty environment, and decomposes it into several relatively-simple local sub-problems based on ontology concept. Then diagnosis agent is respectively designed f...

With the development of substation automation technology, unmanned substation operation mode has become a trend, at present, many substations to achieve the "remote viewing" function, will be the scene of the substation, the equipment state to video image transmission to the remote control center (set control station). And scheduling center (set control station) on live video equipment to contr...
