| Popis: | 106 Shimen Reservoir and Shimen Power Plant is the first multi-purpose hydraulic resource development project for irrigation, flood control, power generation, water supply and sightseeing built after the National Government moved to Taiwan.Shimen Power Plant is a reservoir-type power generation system. The power plant is equipped with two vertical axis Francis turbine generators with a total capacity of 90,000 kilowatt. The total annual generating capacity of each generator is 1.1 billion degrees.Later, because the silt deposits in the Shimen Reservoir were very serious, the Shimen Reservoir Administration in September 1973, through the research report of the engineering consultancy company, completed the 25-meter-high Yixing sand dam heightening project to intercept the Dahan River. The high and low drops formed by the downstream channels are used for hydropower generation. In addition, the Shimen Reservoir Administration approved the approval of the government in July 1983 to complete the Yixing Power Plant in the Ronghua Dam on the upper reaches of Dahanxi. The Yixing Power Plant is an adjustment pool type power generation system. A vertical axis method is installed in the power plant. The water heater has a capacity of 45,000 瓩 and an average annual power generation of 180 million kWh.Shimen Power Plant and Yixing Power Plant are collectively referred to as Shimen Power Plant. Since 2002, the power generated by these two power plants has been transported to the Ruiyuan Primary Substation in parallel with the Taipower Power System via a 161KV dual-circuit transmission line, and then by Taipower. The company unified collective dispatch,transportation, operation and sales to provide the power of northern Taiwan. Although hydropower is the most mature technology to develop, hydropower is dependent on the weather. When the rainfall is reduced and the river encounters a dry season, the hydropower plant's generator set cannot generate electricity.Restricted rivers in Taiwan are short, geologically fragile, and the location of excellent hydropower plants is limited. The reservoirs that have been built are faced with serious siltation and low water storage problems,and the reservoirs are not based on power generation as a priority, but with people's livelihood, public water, agriculture. Irrigation and other adjustment policies, in the dry season, the priority is to supply electricity for people's livelihood. Therefore, 2/3 of the hydropower plants are forced to stop generating electricity, which is only used to regulate power generation during peak hours. Limited for the development of hydropower. |
