2: * 分析解析COMTRADE（IEEE标准电力系统暂态数据交换通用格式）文件格式。
3: *
4: * （一）IEEE的COMTRADE数据格式
5: *
6: * COMTRADE是IEEE标准电力系统暂态数据交换通用格式。标准为电力系统或电力系统模型采集到的暂态波形和事故数据的文件定义了一种格式。
7: * 该格式意欲提供一种易于说明的数据交换通用格式。IEEE于1991年提出，并于1999进行了修订和完善。每个COMTRADE记录都有一组最多4个与
8: * 其相关的文件，4个文件中的每一个都具有一个不同的信息等级。4个文件如下：
9: *
10: * （1）、标题文件（xxxxxxxx.HDR）
11: * 标题文件是由COMTRADE数据的原创者建立的一种可选的ASCII文本文件，标题文件的创建者可以以任何需要的顺序创建任何信息。标题文件的
12: * 格式为ASCII。
13: *
14: * （2）、 配置文件（xxxxxxxx.CFG）
15: * 配置文件为一种ASCII文本文件，用于正确地说明数据（.DAT）文件的格式，因此必须以一种具体的格式保存。该文件诠释了数据（.DAT）文
16: * 件所包含信息，其中包括诸如采样速率、通道数量、频率、通道信息等项。配置文件第一行中的一个字段识别文件所依照的 COMTRADE标准版
17: * 本的年份（例如1991、1999等）。如果该字段不存在或是空的，则假设文件则遵照标准的最初发行日期（1991）。配置文件还包含识别伴随
18: * 的数据文件是以ASCII格式还是以二进制格式存储的字段。 配置文件有下列信息：
19: * （a）站名，记录装置的特征，COMTRADE 标准的修改年份
20: * （b）通道的数量和类型
21: * （c）通道名称、单位和转换系数
22: * （d）线路频率
23: * （e）采样速率和每一速率下的采样数量
24: * （f）第一数据点的日期和时间
25: * （g）触发点和日期和时间
26: * （h）数据文件类型
27: * （i）时间标记倍乘系数
28: *
29: * （3）、 数据文件（xxxxxxxx.DAT）
30: * 数据文件包含记录中每个采样所有输入通道的值。数据文件包含一个顺序号和每次采样的时间标志。这些采样值除记录模拟输入的数据之外，
31: * 也记录状态，即表示开/关信号的输入。
32: *
33: * （4）、 信息文件（xxxxxxxx.INF）
34: * 信息文件是一种文件创建者希望使之对用户有用的信息之外的特别信息。信息文件是可选文件。
35: *
36: * COMTRADE定义的所有文件，都在IEEE 标准电力系统暂态数据交换通用格式Std C37.111-1991或IEEE Std C37.111-1999版本中进行了诠释。
37: *
38: * （二） 电力系统故障动态记录技术准则
39: *
40: * 电力行业标准《220kV~500kV电力系统故障动态记录技术准则》（DL/T 553-94），是故障录波装置研制和开发中必须依据的标准。标准在3.6.5
41: * 条中规定了，输出的动态过程记录数据应符合的标准格式与ANSI/IEEE Std C37.111-1991 COMTRADE兼容。同时，标准规定了电力系统发生故障
42: * 的整个过程中，模拟量采集方式的数据记录按时段顺序进行。
43: * A时段：系统在扰动开始前的状态数据，直接输出原始采集波形，记录时间≥0.04S
44: * B时段：系统大扰动初期的状态数据，直接输出原始采集波形，记录时间≥0.1S
45: * C时段：系统大扰动后的中期状态数据，可输出连续工频有效值，记录时间≥1.0S
46: * D时段：系统动态过程数据，每0.1S输出一个工频有效值，记录时间≥20S
47: * E时段：系统长过程的动态数据,每0.1S输出一个工频有效值,记录时间≥10min
48: * 这里，技术标准的数据记录有两个主要特点，一是分段记录，二是记录的数据不仅可以有按某一采样率的采样数据，而且可按一定间隔记录有效
49: * 值以代替采样值。
50: *
51: *（三） 微机故障录波装置和COMTRADE文件
52: *
53: * 微机故障录波装置，基本配置分为一台采集站和一台分析站，采集站和分析站之间通过高速以太网连接。采集站负责采集、记录故障数据；采集
54: * 站采集的原始数据或记录的原始故障数据，除了存入采集站的硬盘保存外，还将通过网络把数据上传到分析站。分析站程序采用VC 6.0编制，完
55: * 成对数据处理、波形显示、自动分析、与远方通信功能。数据处理中，自动生成符合COMTRADE格式的文件。装置接收故障采样数据后，直接将数
56: * 据处理成COMTRADE数据格式的文件。故障录波装置模拟量采样频率为5000次/秒，采样时段根据电力系统故障动态记录技术准则，做了相应调整，
57: * 将C时段调整为直接输出原始采集波形，记录时间≥1.0S，这样ABC时段采样频率为5000次/秒，存实时的模拟数据；而DE时段采样频率为10次/秒，
58: * 用存最大值数据来代替有效值，这样便于产生包络线波形。我们省略了标题文件和信息文件，并且根据不同的批次和故障次数，定义文件名，生
59: * 成的配置文件( DIR00．CFG )和数据文件( DIR00．DAT )，并同时存放于同一批次文件夹DIR00内。文件示例如下列所示。
60: *
61: * （1）、配置文件( DIR00．CFG )
62: * 城东变电所,03 【注：变电站名称 录波器编号】

66: * 其中：实际值y与采样记录数据X的关系：y = fCoefA * X + fCoefB, 所以实际的最值：
67: * Min = fCoefA * fMin + fCoefB; Max = fCoefA * fMax~ + fCoefB; 】

86: *
87: *（2）、 数据文件( DIR00．DAT )
88: * 1, 0, 46, -54, 10, 0, 1204, -734, -442, 60, 0, 1, 0, 1 【注：依次为：序号，采样时间，模拟采样记录值[按cfg文件的顺序],数
89: * 字采样记录值[按cfg文件的顺序]，其中模拟量实际值算法：y = fCoefA * X + fCoefB, 同最值计算方法；如：
90: * 对于46表示的实际值y为：y = fCoefA（即8.46830338） * X（即46） + fCoefB（即0.00000000）
91: * 对于－54表示的实际值y为：y = fCoefA（即8.46830338） * X（即－54） + fCoefB（即0.00000000）
92: * 对于10表示的实际值y为：y = fCoefA（即8.46830338） * X（即10） + fCoefB（即0.00000000）
93: * 对于0表示的实际值y为：y = fCoefA（即0.15540126） * X（即0） + fCoefB（即0.00000000）
94: * 对于1024表示的实际值y为：y = fCoefA（即0.15540126） * X（即1024） + fCoefB（即0.00000000） 】
95: * 2, 200, 48, -54, 6, 0, 1218, -682, -504, 60, 0, 1, 0, 1
96: * 3, 400, 50, -52, 4, -2, 1206, -616, -554, 58, 0, 1, 0, 1
97: * 4, 600, 52,-50, -2, 0, 1192, -542, -614, 56, 0, 1, 0, 1
98: *
99: * 注：以上说明文字部分来自网络。
100: *
101: * 另外，对于Binary保存方式的数据文件（dat文件），数据保存格式为：序号[4字节]、采样时间[4字节]、模拟量值[按cfg文件的顺序，两字节
102: * 表示一个模拟量采样值]、数字量组值[按cfg文件的顺序，16个数字量一组，一组用2字节表示，不够一组的空位（高位）补零构成一组，组内
103: * 从低位bit依次到高位bit与cfg文件里的数字量顺序对应]。
104: *
105: * 经验表明，目前大部分comtrade文件中的cfg文件中所表示的通道最值与dat中实际的最值都是不相符（出入很大），所以在读dat的接口中引入
106: * 了最值统计。
107: *
108: * 本代码支持win32平台和linux平台。
