发电小时拐点发电设备利用小时数据的变化不单是受电力供需关系的影响,而且也直接受电源结构变化的影响,特别是受与火电相比其发电设备出力率较低的水电、风电规模变化的影响。从历史经验来看,火电设备平均利用小时数在5300小时以下,表明全国电力供需平衡有余,5300小时到5700小时表明供需紧张,超过5700小时就是缺电状态。
Hourly Turnover of Power Generation Equipment The change of utilization hours of power generation equipment is not only affected by the power supply and demand but also directly affected by changes in the power supply structure. In particular, due to changes in the scale of hydropower and wind power with lower power generation equipment output rates compared with thermal power influences. From historical experience, the average utilization hours of thermal power equipment below 5300 hours, indicating that more than the balance of electricity supply and demand across the country, 5300 hours to 5700 hours that supply and demand tensions, more than 5700 hours is the power shortage.
