Wind power industry development is one focus of clean energy. From the perspective of industrial agglomeration effect, this paper studied the development of Chinese wind power industry chain. The location quotient (LQ) was used to research the wind power industry agglomeration in North China, Northeast China, Northwest China and Jiangsu coastal areas, and it proves that wind power industry agglomeration is existented in the four regions. The concentration ratio (CR) was used to research the market concertration in these regions, and it proves that the different industial agglomeration degree may lead to different characteristics of wind power industry. The result is that we should connect wind power industry chains in China to promote national industrial development, like the power transmission from west to east.

Series Capacitor

The Characteristics of FSC (Fixed Series Compensation) and TCSC (Thyristor Controlled Series Capacitor) damping power-angle oscillation and increasing the limit of power transmission were analyzed. FSC can damp the power-angle in a certain extent. Based on the linear control combined with Bang-bang control strategy, TCSC can damp power-angle effectively. In the cases of only FSC, only TCSC and their combinations, simulation results demonstrate that TCSC is more effective than FSC in damping power-angle oscillation. A conclusion is made that taking effect and cost into consideration, TCSC and FSC in a certain percentage is appropriate.

Wind Turbine System

In transmission line, the series compensation is used to improve stability and increases the power transmission capacity. It generates sub synchronous resonance (SSR) at turbine-generator shaft due to the interaction between the series compensation and wind turbine system. To solve this, several methods have been presented. However, these provide less performance during contingency period. Therefore, to mitigate the SSR and also to improve the dynamic performance of hybrid wind and PV system connected with series compensated wind farms, the adaptive technique of the Black Widow Optimization algorithm based Fuzzy Logic Controller (BWO-FLC) with UPFC is proposed in this paper. Here, the objective function is solved optimally using BWO technique. Based on this, the Fuzzy Logic Controller is designed. The results proved that the proposed controller performs the mitigation of SSR. The damping ratios of proposed controller to mitigation of SSR are 0.0098, 0.0139, and 0.0195 for wind speed of 6, 8 and 10 m/s respectively.

The overvoltage calculation of 750kV transmission line with series compensation has great significance on the design, insulation coordination and protection of the line. In this paper, a transient model of 750kV power transmission system with series compensation is established. Effects of different capacity on no-load capacitive rise overvoltage, single-phase grounding overvoltage, two-phase grounding overvoltage are calculated. Secondary arc current and recovery voltage of different series compensation capacity in single-phase grounding is also calculated.

Important Significance

Inner Mongolia region is vast, and developable wind resource accounts for 50%. However, wind power grid has become the local wind development's main bottleneck. Therefore, studying the sustainability of wind power in this region has very important significance. This article from aspects of resource conditions, economic growth, wind power transmission, technical strength and policy environment analyzes the sustainability of Inner Mongolia wind power generation, then draws the conclusion that the bottleneck problem is expected to be solved and the sustainable development is expected to be realized.
