The potential of Fully Rated Converter-based wind turbines (FRC-WTs) on the mitigation of subsynchronous resonances (SSR) in the power system having series-compensated transmission line. IEEE First Benchmark Model (FBM) was featured with Aggregated FRC-WTs to perform the studies. The potential occurrence and mitigation of the SSR in steam turbine were investigated. The Linear Quadratic Regulator (LQR)...
The supplementary excitation damping controller (SEDC) has been proven to be one of the most economical and convenient measures for damping of subsynchronous resonance (SSR). SEDC is a supplementary function of regular excitation system. It is necessary to verify the performance of SEDC equipment before field test. In this paper, a verification method and results of one practical SEDC equipment are...
As the most environmentally friendly source of power generation, wind power turbines is expanding in the grid. It will also have a broad and deep impact on power system stability. In this paper, a comparison of characteristics is made among three mainly used wind turbines currently which are constant speed wind turbine (CSWT), doubly fed induction generator (DFIG), direct drive synchronous generator...
The impact of Static Synchronous Compensator (STATCOM) to the small signal stability of the integration of a large wind farm is studied. First, STATCOM controller with Supplementary Damping Control System (SDCS) is proposed, to enhance damping of power system. And the simulation model is designed in DIgSILENT /PowerFactory. Second, a large scale wind farm equipped with Doubly Fed Induction Generator...
Nowadays low-frequency oscillation of the interconnected power system has become increasingly prominent, and with large quantities of small hydropower connecting grid this problem becomes more seriously. It is very practical and significant to evaluate small signal stability of actual power system timely and efficiently and master its characteristics of small signal stability deeply. Based on the...
Grid interfacing power conversion unit, connecting the renewable energy and utility grid, is a key section of the renewable power generation system, and quality of the generated power passed on to the utility grid greatly relies on the performance of the interfacing unit. In order to suppress the interfacing unit output current harmonics around integral multiple switching frequency more effectively,...
