1、电力专业英语阅读：作业三：将下列段落翻译成中文Like conventional power plants, wind power plants must provide the power quality required to ensure the stability and reliability of the power system it is connected to and to satisfy the customers connected to the same grid. When wind energy development began, wind power plan
2、ts were very small, ranging in size from under one megawatt to tens megawatts with less than 100 turbines in each plant. Thus, the impact of wind power plant on the grid was very small, and any disturbance within or created by the plant was considered to be in the noise level. In the past 30 years,
3、the size of wind turbines and the size of wind power plants have increased significantly. Notably, in Tehachapi, California, the amount of wind power generation has surpassed the infrastructure for which it was designed. At the same time, the lack of rules, standards, and regulations during early wi
4、nd development has proven to be an increasing threat to the stability and power quality of the grid connected to a wind power plant. Fortunately, many new wind power plants are equipped with state of the art technology, which enables them to provide good service while producing clean power for the g
5、rid. The advances in power electronics have allowed many power system applications to become more flexible and to accomplish smoother regulation. Applications such as reactive power compensation, static transfer switches, energy storage, and variable-speed generations are commonly found in modern wi
6、nd power plants. Because a wind power plant is connected to the grid, it is very important to understand the sources of disturbances that affect the power quality. In general, the voltage and frequency must be kept as stable as possible. 像传统的发电厂，风力发电厂必须提供所需的，以确保电力系统它被连接到的稳定性和可靠性，以满足连接到同一电网的客户的电力质量。当
7、风电发展开始，风力发电厂都非常小，大小不等，从下 1 兆瓦到几十兆瓦，在每个工厂不到 100 台风机。因此，风力发电设备的对电网的影响是非常小的，而且内或由所述植物产生的任何干扰被认为是在噪声电平。在过去的 30 年中，风力涡轮机的大小和风力发电厂的规模已经显著增加。值得注意的是，在Tehachapi 的，加利福尼亚州，风力发电量超过了为它的设计的基础设施。与此同时，早期风发育过程中缺乏规则，标准和法规已被证明是一个日益严重的威胁到连接到风力发电厂的电网的稳定性和功率质量。幸运的是，许多新的风力发电厂都配备了最先进的技术，使他们能够提供良好的服务，同时生产清洁电力的电网状态。在电力电子技术的进步已经使许多电力系统应用变得更加灵活，并实现平滑的调节。应用程序，如无功补偿，静态转换开关，储能，和变速代现代风力发电厂是常见的。因为风力发电站被连接到电网，这是非常重要的是要了解影响电源质量扰动的来源。在一般情况下，在电压和频率必须保持尽可能稳定。
