編制动力系統的規划应根据各部門的要求和系統的發展远景。在編制过程中,首先应研究本区域內水力資源的开發情况,更应仔細研究在綜合利用方面具有意义的大水力樞紐的建筑。当水力资源不足或建筑时間来不及以及由於其他原因(如洗煤的利用,供热等)不能修建水电站时,再考虑配备相当的热电站和火电站。这样就可以形成一个水火电站並列运行的 The preparation of power system planning should be based on the requirements of various departments and the development perspective of the system. In the preparation process, the development of the hydropower resources in the region should be studied first, and the construction of a large hydraulic hub with significance in comprehensive utilization should be carefully studied. When the hydropower resources are insufficient or the construction time is too late and due to other reasons (such as the use of coal washing, heating, etc.) when the hydropower station cannot be built, consider the allocation of equivalent thermal and thermal power stations. In this way, a hydrothermal power station can be formed in parallel.
