HuffMan
哈夫曼编码译码系统,设置发送者和接受者两个功能,
发送者的功能包括:
①输入待传送的字符信息;
②统计字符信息中出现的字符种类数和各字符出现的次数(频率);
②根据字符的种类数和各自出现的次数建立哈夫曼树;
③利用以上哈夫曼树求出各字符的哈夫曼编码;
④将字符信息转换成对应的编码信息进行传送。
接受者的功能包括:
①接收发送者传送来的编码信息;
②利用上述哈夫曼树对编码信息进行翻译,即将编码信息还原成发送前的字符信息。
(Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)

低频减载的MATLAB仿真模型
说明: 电力系统的频率反映了发电机组所发出的有功功率与负荷所需的有功功率之间的平衡情况。当系统发生较大事故时,系统出现严重的功率缺额,其缺额值超出了正常热备用可以调节的能力,这时即使令系统中运行的所有发电机组都发出其设备可能胜任的最大功率,仍不能满足负荷功率的需要,所引起的系统频率下降值将远远超出系统安全运行所允许的范围。 在这种情况下从保障系统安全运行的观点出发,为了保证电网安全和对重要用户的供电,不得不采取应急措施,切除部分负荷,以使系统频率恢复到可以安全运行的水平内。(The frequency of the power system reflects the balance between the active power generated by the generating unit and the active power required by the load. When the active power from the power plant does not meet the requirements of users, the system frequency will decrease. Frequency fluctuation caused by unplanned load in normal operation of the system. At this time, the system uses the hot standby capacity of the power plant, that is, the generator capacity in the system operation is enough to meet the needs of users. However, when the system has a major accident, the system has a serious power shortage, which is beyond the adjustable capacity of normal hot standby. At this time, even if all the generating units operating in the system send out the maximum power that their equipment may be competent for, they still cannot meet the demand of load power rate, and the resulting system frequency drop value will be far beyond the allowable range of safe operation of the system.)
