This guide presents information regarding the essential subsystems that make up a fossil-feuled unit-connected boiler-turbine-generator (BTG) station and describes typical interlocking, control, and protection for operating them in a coordinated order to ensure proper start-up and safe shutdown. The primary purpose of this guide is to provide a basis for (1) Qualitative evaluating of overall design of a unit-connected fossil fuel plant (2) Writing general operating guides of an educational… read more nature, thereby serving to aid in acquainting personnel with boiler-turbine-generator systems. Every new fossil plant will have its own special operating sequence due to the type of equipment installed and its operating company's practices. However, this guide purports to include in one document a description of various cycles in a power plant, their sequence of operation, and protection procedures. The information contained in this guide should be coordinated with manufacturers' recommendations to establish individual plant designs. read less

This standard specifies a communication layer, Flexible Optical Service Unit (OSUFlex) to provide small service channels in optical transport networks. The main features of the OSUflex communication layer are providing massive OSUflex connections to directly carry power services (e.g. E1 or IEEE C37.94) into an optical transport network, enabling the flexible bandwidth (e.g. n × 2 Mb/s) and hitless bandwidth adjustment for each OSUflex connection, direct mapping of services into OSUflex with… read more the capabilities of high-bandwidth efficiency, low latency, low latency jitter and high-precision clock synchronization for power system applications. read less
