Damping analysis of sub-synchronous resonance (SSR) in a wind farm based on DFIG in a series compensated network
The effect of wind generator on sub-synchronous resonance (SSR) is being interested by increasing penetration of wind turbine in power systems,. Purpose of this article is to analyze SSR in a wind farm based on doubly fed induction generator (DFIG) which is connected to compensating series grid. A dynamic model for analysis of induction generator effect and Torsional Interaction (TI) has been u...
متن کاملComparative Analysis of DFIG Based Wind Farms Control Mode on Long-Term Voltage Stability
The wind energy industry is experiencing a strong growth in most countries in the last years. Several technical, economic and environmental benefits can be attained by connecting wind energy to distribution systems such as power loss reduction, the use of clean energy, postponement of system upgrades and increasing reliability. The doubly fed induction gen‐ erator (DFIG) is currently the most c...
متن کاملDynamic Stabilization of Wind Farms Deploying Static Synchronous Series Compensator
Encountering series-compensated transmission lines, sub-synchronous resonance (SSR) may strike the power system by jeopardizing its stability and mechanical facilities. This paper aims to verify the capability of static synchronous series compensator (SSSC) in mitigating the mechanical and electrical oscillations such as SSR in wind farm integrations. A wind turbine with a self–excited inductio...
متن کاملApplication of an Additive Self-tuning Controller for Static Synchronous Series Compensator for Damping of Sub-synchronous Resonance Oscillations
In this paper, an additive self-tuning (ST) control scheme is presented for a static synchronous series compensator (SSSC) to improve performance of conventional PI control system for damping sub-synchronous resonance (SSR) oscillations. The active and reactve series compensation are provided by a three-level 24-pulse SSSC and fixed capacitor. The proposed ST controller consists of a pole shift...
متن کاملA Microprocessor-Based Sub-Harmonic Protection Technique for Wind Farms
Wind farms are generally located far away from load centers and, to increase the power flow, series capacitors are normally installed to compensate the transmission line reactance. The interaction of the series capacitor with the wind system can cause undamped sub-harmonic (below 60 Hz or 50Hz system frequency) current and voltage oscillations, which can cause serious damage to wind turbine con...
