生成comtrade格式数据的代码

由于comtrade格式数据包含了很多细节，因此生成comtrade格式数据的代码会比较复杂。以下是一个Python代码示例，可以生成一个包含两个通道的comtrade格式数据文件：

import datetime

def generate_comtrade_file(file_name, start_time, sample_rate, num_samples, channel_names, channel_units, channel_data):
    # Generate file header
    header = []
    header.append("C 1.1")
    header.append("SAMPLES=" + str(num_samples))
    header.append("CHANNELS=" + str(len(channel_names)))
    header.append("DATE=" + start_time.strftime("%Y%m%d"))
    header.append("TIME=" + start_time.strftime("%H%M%S"))
    header.append("TIMBASE=" + str(1/sample_rate))
    header.append("TRIGGER=EXTERNAL")
    header.append("NOMINAL_FREQ=60")
    header.append("DATA_ENCODING=BINARY")
    header.append("BYTE_ORDER=HIGH_BYTE_FIRST")
    header.append("TIME_MULT=1.000000E-06")
    header.append("FILENAME=" + file_name)
    header.append("TIME_CODE=LOCAL")

    # Generate channel information
    channel_info = []
    for i in range(len(channel_names)):
        channel_info.append("CHANNEL," + str(i+1) + "," + channel_names[i] + "," + channel_units[i] + "," + "A" + "," + "N")

    # Write header and channel information to file
    with open(file_name, "w") as f:
        f.write("\n".join(header) + "\n")
        f.write("\n".join(channel_info) + "\n")

    # Generate data block
    data_block = bytearray()
    for i in range(num_samples):
        for j in range(len(channel_names)):
            data_block += channel_data[j][i].to_bytes(2, byteorder='big', signed=True)

    # Write data block to file
    with open(file_name, "ab") as f:
        f.write(data_block)

# Example usage
start_time = datetime.datetime(2021, 1, 1, 0, 0, 0)
sample_rate = 1000
num_samples = 1000
channel_names = ["Channel 1", "Channel 2"]
channel_units = ["V", "A"]
channel_data = [[i/1000 for i in range(num_samples)], [0.5 for i in range(num_samples)]]
generate_comtrade_file("test.cfg", start_time, sample_rate, num_samples, channel_names, channel_units, channel_data)

这段代码生成的comtrade格式数据文件名为`test.cfg`，包含了两个通道，一个通道是电压信号，另一个通道是电流信号，每个通道包含了1000个采样点，采样率为1000Hz。可以根据需要修改这些参数来生成不同的comtrade格式数据文件。
