负荷变动 meaning in English
load change
load variation
Examples
- The performance of the control systems of units directly influences the safety and economy of units
热工控制系统的性能对机组运行的安全性和经济性都有着直接的影响,尤其是对负荷变动较为频繁的机组。 - Many uncertainties such as power supply and fluctuating load still exist even if a certain transmission network structure has set up in planning period
在电网规划阶段,网架结构确定之后,还存在着诸如电源出力和负荷变动等不确定因素。 - The rule for the determination of the optimal installation places is put forward with the consideration of reactive load changes . the method for reactive power optimal compensation based on the optimal incremental active loss is investigated in details . the impact of reactive power compensation on network voltages is discussed in the following
在无功优化方面,探讨了无功补偿装置的最佳安装地点,并给出了无功负荷变动情况下无功补偿装置最佳安装地点的选择原则,深入分析了按无功经济当量的无功最优补偿方法以及补偿对配电网电压的影响。 - 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。
