Wind generation and wind farms are becoming an important part of the generating capacity of the modern utility grid. Protection of wind turbines, and wind farm collector systems, has been the subject of numerous technical papers over recent years, as wind generation grows more prevalent. These papers have focused on the basics of protecting the wind turbines, protecting the wind farm, and modelling...
This paper discusses the topic of Control Systems within the Electricity industry. Distributed, Centralised, Regional are a small example of the varied types discussed. The purpose is to define the solution for a specific problem/requirement utilising the appropriate architecture of a 'Control System', rather than proposing a control system and tailoring the requirement accordingly.
Increasingly, communications has become a significant component in modern power systems. The recently introduced standard IEC61850, describes the concepts for sub-station communications covering protection, control and metering functions. Not only is this is going to have a major impact on the power systems communications but it will also influence the design of future protection systems. The concepts...
It has always been a challenge to perform extensive functional tests on protection and control panels, encompassing both most likely and unlikely scenarios that could happen in a substation environment.
Due to the advancement of technologies, Intelligent Electronic Devices, (IED's) can handle multiple protection and control function. IEC61850 standard allows high levels of data that can be exchanged between IED's from different product suppliers. These developments will enable innovative re-design of the secondary substation protection systems compared with current industry practices, where different...
The paper investigates the current capabilities in communication-aided protection made possible by the IEC 61850 standard. Additionally, it explicitly describes the concept of integrated protection unit and the IEC61850-9-2 process bus concept. It also discusses techniques to encompass intersubstation communications and examines issues that need to be addressed to create a successful, secure and dependable...
This paper developes a fault diagnosis system based on IEC61970 and IEC61850 standard series. The key problems in fault diagnosis system are the deficiency and standardization of distributed fault information. This fault diagnosis system get fault information mainly from SCADA and fault information system. The information from SCADA, including network topology and switch state, is modeled based on...
