预报准确度 meaning in English
forecast accuracy
Examples
- It also shows that the software interface is friendly and the forecast accuracy is up to the standard , which meets the demand of the consumers . this system improves the operating management of power system to a higher level , and has a better practical application value
该系统的实际运行表明，所用模型合理，软件界面友好，功能完善，操作简单，预报准确度达到了部颁标准，满足了用户需求，提高了电力系统运行管理水平，具有较好的实际应用价值。 - This system adopts cumulatively autoregressive moving average model [ arima ] of time series method and modified model gm ( 1 , 1 ) of grey system , makes a local load forecasting modeling through the integration of the above two models and also preprocesses the daily load during the sudden change of climate , thus greatly improving the forecast accuracy . the practical operation indicates that the model is reasonable and easy to operate with complete function
本系统在经过反复试算后，在算法上采用了时间序列法的累积式自回归动平均模型( arima )与灰色系统中的gm ( 1 ， 1 )改进模型，并将两种模型组合用于该地区负荷预报建模，另外还对气候急变日负荷进行了预处理，大大提高了预报准确度。 - Because of the randomness , the periodicity and the impact property of load changes , the short - range electric load forecasting accuracy is related to the pre - processing of original data , the load forecasting model , the sudden change of climate etc . without an appropriate mathematical model , it is difficult to meet the demand of farecasting accuracy by using computer software
短期电力负荷预报的准确度与原始数据的预处理、负荷特性、预报模型、气候突变等因素有关，因为负荷变动具有随机性、周期性和冲击性的特性，如果不采用恰当的数学模型，利用计算机软件技术就难以满足预报准确度要求。
