Dynamic Harmonic Modeling and Analysis of VSC-HVDC Systems
Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs a Dynamic Harmonic Domain (DHD) based framework for dynamic harmonic analysis of VSC-HVDC systems. These systems are wide...
متن کاملOptimal PMU Placement Considering with HVDC Links and Their Voltage Stability Requirements
In wide area measurement systems, PMUs are the main component measuring real time synchronized data from different buses. Installation of PMUs at all buses is a primary way to provide full observability of the power network. However, it is not practical in real networks due to the relatively expensive cost of PMUs and other technical limitations. Optimal PMU Placement (OPP) is an optimization p...
متن کاملInvestigation of Hybrid Pseudo Bipolar HVDC Performances Supply Power to Passive AC Network
The traditional HVDC plays an important role in the development of power grid. But the traditional HVDC cannot supply power either to entirely passive AC network or to weak AC system. In fact, an entirely passive AC network can be effectively powered through VSC-HVDC. However, the cost of investment in VSC-HVDC is amazingly high due to the limitation of power electronics technology. Based on CS...
متن کاملA Paper of Determination of Controlling Characteristics of the Monopolar HVDC System
Due to cost effectiveness and less electrical fault hazards, the HVDC transmission is more suitable for long distance power transmission than that for the conventional AC transmission system. Moreover the utilization of power electronics has made HVDC technology competitive and reliable in comparison to HVAC system. The controlling mechanism of the DC link (either monopolar or bipolar) is the m...
متن کاملPerformance of Hybrid Reactive Power Compensators in a Multi-terminal Hvdc Transmission System Feeding Weak Ac Networks during Transient Fault Conditions
In this paper performance analysis of various hybrid reactive power compensators (RPC’s) at the inverter AC sides of a line commutated converter (LCC) based multi-terminal HVDC (MTDC) transmission system, feeding weak AC networks, is carried out to thoroughly gather the mechanisms of interactions between an HVDC system and weak AC systems. The hybrid compensator is realized by equally mixing th...
