SCADAError¶
SCADAError 类用于处理和分析SCADA系统中的故障数据。它的构造函数接收故障数据、风机字段、故障开始和结束时间字段、故障类型字段以及故障分析方法（如故障次数和停机时间）作为参数。这些参数用于初始化类实例，以便对故障进行系统化分析。
SCADAError(data, wind_field,start_time_field,end_time_field,error_type_field,function)¶
初始化 SCADA 故障分析类后，该类可以分析 SCADA 数据中的故障时间、故障次数，并对故障进行详细分类统计。具体的故障类别包括变流器故障、变桨故障、偏航故障、主控故障、发电机故障、润滑故障、水冷故障以及其他故障。这种分类和分析有助于全面了解和管理风机的运行状态及维护需求。
参数：
data(DataFrame): 故障数据。wind_field(str): 风机字段。start_time_field(str): 故障开始时间字段。end_time_field(str): 故障结束时间字段。error_type_field(str): 故障类型字段。function(Callable): 故障分析方法，接受的功能包括故障次数、停机时间等。
使用示例
data = pd.read_csv('wtai_dt/SampleData/SCADA_Error/SampleErrorScada.csv')
scada_error = SCADAError(data, 'event_unit','event_start_time','event_end_time','event_type','故障次数')
scada_error.error_analysis()¶
根据初始化定义的参数，该函数利用 function 字段分析 SCADA 故障数据，计算故障次数和停机时间。该功能旨在帮助用户高效管理和评估风机运行状态，确保数据的准确性和可追溯性。
参数
使用示例
scada_error = SCADAError(data, 'event_unit','event_start_time','event_end_time','event_type','故障次数')
scada_error.error_analysis()
T28-04 故障次数6
T29-04 故障次数3
T30-04 故障次数14
scada_error.error_statistical(type,save_flag)¶
根据初始化时定义的参数，该函数根据 type 参数分析 SCADA 系统中的故障或警告数据，并对这些数据进行分类处理。该函数生成多种统计图表，包括各风机的故障类型总统计图、故障类型专门统计图、报警类型统计图以及故障类型分类统计图。根据 save_flag 参数的设置，函数可选择性地将这些结果图像保存下来，以供进一步分析和参考。
参数：
type(str): 故障类型、警告类型save_flag(bool): 分析结果图片保存标志
使用示例
scada_error = SCADAError(data, 'event_unit', 'event_start_time', 'event_end_time', 'event_number', '故障统计')
scada_error.error_statistical('故障',True)
