本文详细介绍了一类重要的方程-福克普朗克方程，是一本针对研究生的好书(This paper describes an important class of equations- Fokker-Planck equation, is a good book for graduate students)

说明：  下垂控制就是选择与传统发电机相似的频率一次下垂特性曲线（Droop Character）作为微源的控制方式，即分别通过P/f下垂控制和Q/V下垂控制来获取稳定的频率和电压，这种控制方法对微网中的微源输出的有功功率和无功功率分别进行控制，无需机组间的通信协调，实现了微源即插即用和对等控制的目标，保证了孤岛下微电网内电力平衡和频率的统一，具有简单可靠的特点(Droop control is to choose Droop Character, which is similar to the traditional generator, as the control mode of micro-source, that is, to obtain stable frequency and voltage through P/f droop control and Q/V droop control respectively. This control method controls active power and reactive power of micro-source output in micro-grid separately, without communication coordination between units. The goal of micro-source plug-and-play and peer-to-peer control is realized, which ensures the unification of power balance and frequency in the micro-grid under isolated islands, and has the characteristics of simplicity and reliability.)

美国Richard O.Duda编著的pattern classification，是学习模式识别的好书，里面含有中英文两个版本，希望对大家学习有帮助！(The United States, Richard O.Duda compiled pattern classification, learning pattern recognition book, which contains two versions of Chinese and English learning!)

说明：  经纬度转ECEF坐标公式 高精度 非迭代(The formula of latitude and longitude to ECEF coordinate)

Labview双通道信号采集，实现双通道同时采集与数据保存，简单易用(Labview dual channel signal acquisition, double channel simultaneous acquisition and data storage, simple and easy to use)

OPC DA Server 2.0的实现，实现了异步及订阅的方式(The implementation of OPC DA Server 2 implements asynchronous and subscription methods)

柔性直流输电技术是比传统直流输电更先进的直流输电技术。所以除了拥有传统高压直流输电技术即可以控制有功功率又可以控制无功功率、输电距离基本不受限制、直流输电比交流输电更稳定、实现异步系统互联和减轻环境影响的优点，柔性直流输电还具备许多自身特有的优点。(Flexible HVDC transmission technology is more advanced than traditional HVDC transmission technology. Therefore, in addition to the advantages of traditional HVDC technology, such as active power control and reactive power control, almost unlimited transmission distance, more stable HVDC than ac transmission, asynchronous system interconnection and environmental impact reduction, flexible HVDC also has many unique advantages.)

说明：  发电机接入三相不平衡负载，三相负载大小不同，但阻抗角相同，实现三相幅值不平衡仿真(The generator is connected to a three-phase unbalanced load, the three-phase load is different in size, but the impedance angle is the same, and the three-phase amplitude imbalance simulation is realized)
