Wind Power Plant

RDS-PP (Reference Designation for Power Plants) is a new identification system for power plants, which basis and structure are based on international standards. With the purposes to meet the designation of new power plants like wind power plant, KKS (Kraftwerk-Kennzeichen system) is developed to RDS-PP. VGB technical committee recommends newly-built power plants adopts RDS-PP directly. Though leading to additional work, adopting new identification system have a long term economic effect.

Wake Effect

A technical and economic model of a wind power plant has been developed. Parameterization was carried out and the main parameters of the wind power plant were identified. Statistical relationships of parameters with capital investments in wind turbines and costs of their operation and maintenance were established. The criterion for the search for optimal parameters is taken as the minimum discounted unit costs for the production of electrical energy for the economic life of the wind power plant. To do this, the electricity production in a wind power plant must be maximized by reducing the so-called wake effect that is created in a wind farm due to the shading of some wind turbines by others. The velocity reduction behind each wind turbine is estimated. An algorithm for optimizing the parameters of a wind power plant has been developed. An optimization model was used to determine the parameters of the Hasia wind power plant.

In recent years, the demand for electric power in Vietnam has increased at annual growth rates of 10% to 12%, and the challenge is to promote renewable energy sector. One of these sustainable energy sources is to harness energy from the wind through wind turbines (WTs). In fact, more wind power plants in Vietnam are continuously to be built due to the rapidly growing demand of country's industrialization and modernization process. However, a significant hindrance preventing the widespread use of WTs in Vietnam is the noise they produce, which significantly contributes to the annoyance experienced by residents living near wind farms. The prediction of noise impacts for new wind farms is one of the many aspects of the environmental impact assessment process in Vietnam as well as in the world. In addition, the determination of the 45 dBA noise contour-line is very important because it is the basis for determining the scope of the project impact according to the IFC/WB performance standards and the number of households to be relocated from the project site. The article’s main focus is therefore on the estimation and simulation of the acoustical noise produced by 18 WTs during the operation phase of Nexif Energy Ben Tre wind power plant and the background noise levels at the project site have been performed by using a combination of specific study methods such as environmental modeling (iNoise Pro modeling software), mapping and geographic information systems. The obtained results show the importance of using modeling method in quantifying the noise levels generated from 18 wind turbines of the Nexif Energy Ben Tre wind power plant met IFC standard and Vietnamese regulation on noise during day-time, but did not meet IFC standard on noise during night-time. The level of background noise measured during night-time in the project area also did not meet IFC standard. Therefore, the overall cumulative noise level exceeds the IFC standard for residential area (45 dBA only). In addition, the appropriate solutions to reduce noise levels from WTs are also proposed.

The Impact

Nowadays a large interest in the public and private sector is dedicated in generating electricity using renewable resources. Thus, over 60,000 MW is produced worldwide by using the wind energy. These systems are generally composed of power plants formed from 2–3 to several tens, hundreds of wind turbines with rotating blades that reach heights over 160m. The number, the height, and the rotation of these wind turbines represent technical challenges for the radar system efficiency and accuracy. They should be assessed carefully, in each case, to ensure that it maintains an acceptable level of the air space surveillance capability. The research paper presents the influence of the wind power farms on the air radars especially in cases of surveillance area, both for the primary radars and the secondary radars. There are differences between the interference between the wind turbines and radars functioning, depending on the types of radars. In the last decades in Romania is a permanent effort to increase the number the wind farms built, or in the process of being built, but also referring at the number of wind turbines in these parks and their physical dimensions. This paper focuses on the effects of the wind farms on the radars efficiency, and their potential impact on the ability of airspace surveillance. This results in a concise and transparent reference guide for developers of wind farms when assessing the impact of wind turbines on aerial surveillance systems. Specialists are relatively unanimous in their opinion that, in order to make an assessment of the impact of the wind farms on the radars must be defined at least three areas corresponding to different levels of the technical expertise. They must be combined with the influence of the wind farms on the ability of the radar to fulfill the mission, why they were installed, assuming that it is necessary to create an exclusive protection area. First, are discussed briefly the principles of the radar’s operation, depending on their type: primary and secondary surveillance radars. Further, are estimated the induced reflections by the wind power plant on the radar system. If the number of false targets generated by the reflections from wind turbines is too big, so it exceeds the processing capacity of the radar, the operational capacity will suffer. There are presented some theoretical aspects, followed by some cases where the proper functioning of the primary and secondary radars is affected. The model is tested in field, at two different distances, with airplanes and helicopter flying at different altitudes, with radar placed near the wind power plant Fantanele – Cogelac, the biggest in Romania. Finally, is estimated the area necessary to assure proper functioning of radars. Some conclusions and references are presented.
