The power flow model of the multiterminal voltage-source converter-based high voltage DC (M-VSC-HVDC) transmission system for large-scale power systems is studied. The mathematical model is derived using the d-q axis decomposition of HVDC's control parameter. The developed model can be applied to all existing shunt voltage-source converter (VSC) based controllers, including Static Synchronous Compensator (STATCOM), point-to-point HVDC system, back-to-back HVDC system and multiterminal HVDC system. A unified procedure is developed for incorporating the proposed model into the conventional Newton-Raphson power flow solver. The IEEE 300-bus test system embedded with multiple HVDC transmission systems under different configurations are investigated. Simulation results reveal that the proposed model is effective and accuracy in meeting various control objectives.

A collaborative engineering environment (CEE) enables the effective capture, management, communication, and exploitation of all product related information to a project team. The systematic employment of this information offers substantial improvements in productivity, cost savings, cycle time reductions, product integrity, and lifetime supportability of the system. Advanced CEE capabilities exploit and leverage the engineering, architectural and technological expertise of enterprise subject matter experts (domain experts) across multiple complex systems development and integration activities. The CEE provides a tightly coupled process automation using reusable product elements for coupling information with engineering processes and ensuring adherence to repeatable and traceable engineering processes. A product catalog provides a single information management point for intrinsic complex product characteristics and facilitates the propagation of that information to engineering teams incorporating the complex product into their system designs. The intrinsic complex product characteristics are augmented with implementation specific information to fully describe the complex product in the system design.

A reusable framework is utilized for creating a software architecture in a Service Oriented Architecture (SOA). After a general framework is created, that general framework is divided into a governance domain and an architecture domain. The architecture domain is further divided into architecture sub-domains within the architecture domain. Activities that are required for the governance domain and each of the architecture sub-domains and identified and described in detail, and owners and progress status markers for these activities are identified. The detailed descriptors of the activities, identified owners and progress status markers are then mapped onto a client-specific System Development Life Cycle (SDLC) work product to create an SOA-based software architecture. Deployment timelines for the governance domain and the architecture domain are determined, and a project plan for deploying the SOA-based software architecture is created.

A multi-mode speech communication system is described that has different operating modes for different speech applications. A speech service compartment contains multiple system users, multiple input microphones that develop microphone input signals from the system users to the system, and multiple output loudspeakers that develop loudspeaker output signals from the system to the system users. A signal processing module is in communication with the speech applications and includes an input processing module and an output processing module. The input processing module processes the microphone input signals to produce a set user input signals for each speech application that are limited to currently active system users for that speech application. The output processing module processes application output communications from the speech applications to produce loudspeaker output signals to the system users, wherein for each different speech application, the loudspeaker output signals are directed only to system users currently active in that speech application. The signal processing module dynamically controls the processing of the microphone input signals and the loudspeaker output signals to respond to changes in currently active system users for each application.
