TCSC: A New Type Of Spatial Crowdsourcing
2019 20th IEEE International Conference on Mobile Data Management (MDM), 2019The popularity of advanced mobile terminals allows spatial crowdsourcing to be widely used. In this work, we study a new type of spatial crowdsourcing, called time-continuous spatial crowdsourcing (TCSC in short). This type of crowdsourcing is primarily concerned with tasks that take a long time to finish and involves time-sharing among multiple ...

A comparative study of three nonlinear controllers for TCSC
2001 IEEE Porto Power Tech Proceedings (Cat. No.01EX502), 2002The paper reviews modeling of thyristor-controlled series capacitors (TCSC) which are highly nonlinear systems with continuous and discontinuous states, and proposes three nonlinear controllers for them: (1) a Lyapunov-based controller; (2) an interconnection and damping assignment (IDA) controller; and (3) a dynamical flatness-based feedback ...

Impact of TCSC control methodologies on subsynchronous oscillations
IEEE Transactions on Power Delivery, 2002This paper presents a detailed analysis of the impact of different TCSC control methodologies on subsynchronous oscillations problem of series capacitive compensated transmission systems. The first IEEE benchmark model for the analysis of SSR phenomena is adopted. The system was evaluated for several different compensation levels.

Mathematical model for describing characteristics of TCSC
Proceedings. International Conference on Power System Technology, 2003The choice of the synchronizing signal has strong impacts on the transient behaviors of TCSC (thyristor controlled series compensation). When the capacitor voltage is used as the synchronizing signal, both overshoot and oscillation occur. However, when the line current is employed, TCSC acts as a first-order lag element.

The Study of an Economic Hybrid TCSC Structure
Applied Mechanics and Materials, 2014The capability to damp sub-synchronous oscillations of single-phase TCSC, two-phase TCSC, three-phase TCSC is comparatively studied in this paper. SVR (Synchronous Voltage Reversal) is used as the control strategy of these three schemes. And IEEE first benchmark model is taken as the simulation example.

Selection of TCSC parameters: Capacitor and inductor
India International Conference on Power Electronics 2010 (IICPE2010), 2011Thyristor controlled series compensator (TCSC) device is a series compensator to govern the power flow by compensating the reactance of the transmission line. Both capacitive and inductive reactance compensations are possible by proper selection of capacitor and inductor values of the TCSC device which can be realized through reactance equation.

Clarification of the SSR mitigation mechanism of a TCSC
Electrical Engineering in Japan, 1997A thyristor controlled series capacitor (TCSC) is considered to be effective not only for flow control and stabilization of power systems, but also for mitigation of subsynchronous resonance (SSR). This paper clarifies the SSR mitigation mechanism of a TCSC.
