实现含风电场RX模型的系统潮流计算，风电场采用RX模型，此模型充分考虑风力发电机的输出功率特性，比其他模型完善，在模型中将迭代过程分为两步:常规潮流迭代计算和异步风力发电机的滑差迭代计算。( In short, the algorithm carried out to simulate the wind farmas an RX bus is as follows: 1)Begin with s=snorm in each machine, snorm being the rated slip of the same. With this value, calculate the impedance Z. 2)With these values, model the wind farm as an RX bus including the admittances of the machines in the admittance matrix and in the corresponding terms of the jacobian. 3)As a result of the first power flow, the voltages in the buses can be obtained. With these, can calculate the mechanical power of the machine. 4)With the value of s, calculate the power extracted the wind with . 5)Compare both powers and, if they are not equal, recalculate，by means of (G) and go to step 2. If they are equal, he algorithm finishes.)

In this paper we present the usefulness of the algorithm DCT (Discrete cosine Transform) blocks applied level image compression JPEG (Joint Photographic Experts Goup). It has been shown that this algorithm is the most efficient in the case of compression because it has very good properties for compaction energy related values. As a basic principle we eliminate high frequencies and keep the low and medium without visibly affecting image. DCT in JPEG compression algorithm is encountered in practical applications such as face detection, skin color, facial recognition, iris, fingerprints
