一年一度的夏季用电高峰即将到来,在市政府和电力部的关心下,近几年上海的电力建设和城市电网的改造获得长足进步,电力供需矛盾有所缓解。但是,每年一到夏季,即使全部发电机组开足,仍有一段时间会出现电力供不应求的矛盾。上海地区的用电负荷对气温变化非常敏感。进入夏季以后,如果连续一个星期气温超过35℃,用电负荷会猛增100余万千瓦,因为电力不能大规模储存,用户用多少电,发电厂就要同时发多少电,严格保持同步平衡,否则电网就要瓦解,造成供电事故。所以,用电负荷的突然增长,对电网的冲击十分厉害。今年预报超过
The annual peak of summer electricity consumption is coming. Under the concern of the municipal government and the Ministry of Electric Power, Shanghai’s power construction and urban power grid reconstruction have made great progress in recent years, and the contradiction between power supply and demand has eased. However, in the summer and the summer of each year, even if all the generator sets are opened, there will still be a period of time when the contradiction of power supply falls short of demand. The electricity load in Shanghai is very sensitive to temperature changes. After entering the summer, if the temperature exceeds 35°C for one week, the electricity load will soar by more than 1 million kilowatts, because electricity cannot be stored on a large scale. How much electricity the user uses, how much electricity the power plant will generate at the same time, and strict balance is maintained. Otherwise, the power grid will collapse, causing power supply accidents. Therefore, the sudden increase in the use of electricity loads has had a severe impact on the power grid. Forecast exceeds this year
