多发展水电还是多发展火电?这是长久以来颇有争论的一个问题。水电和火电是各有利弊的,在电力生产上是相辅相成的。一般说来,火电的特点是:造价低;建设时间短,又便于扩建;易于靠近用户;年利用小时高;但是消耗煤炭多,运转人员多,成本高;本身是个大用电户,即厂用电约占全部发电量的百分之七到八;运转时起动慢,较易发生事故;设备制造耗用钢材多,需要很多优质合金钢,配套很复杂;基本建设用
To develop more hydropower or to develop more thermal power is a subject that has long been controversial. Hydropower and thermal power have their own advantages and disadvantages, and they complement each other in power production. Generally speaking, the characteristics of thermal power are: low cost; short construction time, and easy expansion; easy access to users; high annual utilization hours; but consume more coal, more operating personnel, high cost; itself is a large electricity users, that plant The electricity consumption accounts for about 7% to 8% of the total power generation; the startup is slow during operation and the accidents are relatively easy to occur; equipment manufacturing consumes more steel and requires many high-quality alloy steels; the supporting facilities are very complicated;
