Muchen Reservoir
The Muchen Reservoir Project is a key project for the protection of tens of billions of water resources in Zhejiang Province, exclusively invested by the Group. The project is located on the main stream of the Lingshan River, a tributary of the right bank of the Qujiang River in the upper reaches of the Qiantang River, and belongs to Muchen Township, Longyou County. It is a large-scale water conservancy project that focuses on flood control, power generation, water supply, and improves the water environment. It has a total storage capacity of 125 million cubic meters and a total investment of 450 million yuan. The project is mainly composed of a barrage, a spillway, a vent tunnel, a power tunnel, a power plant, and a booster station. The barrage is a concrete face rockfill dam with a maximum height of 55.8 meters, a dam length of 429 meters, and a dam crest width of 5.5 meters. The spillway adopts a bank-type positive channel spillway, with 3 arc gates, a net width of 12 meters without holes, and the total length of the power diversion tunnel. ? Meters, the power plant is equipped with 2 vertical-axis Francis hydro-generator sets with a single unit capacity of 6,300 kilowatts. The construction of the project started on December 31, 2006, and the dam was closed for impoundment on April 29, 2009, and the power station was on August 5 Put into production to generate electricity. To
After the completion of the project, the flood control standard of Longyou County was raised to once in 50 years, so that the urban areas on both sides of the downstream bank were protected from flooding. It can provide 104.1 million cubic meters of freshwater resources downstream and provide 38.33 million kilowatt-hours of electricity for the local area each year, which is of great significance for improving the investment environment and promoting economic development in Longyou County. The project won the China Water Conservancy Project Quality (Dayu) Award in 2014.
Xiaoxitan Water Control Project
The Longyou Xiaoxitan Water Conservancy Project is an important project for the group company to take advantage of the company's own advantages and participate in industrial investment.
The Xiaoxitan Water Conservancy Project is located in the territory of Longyou in the middle reaches of the Qiantang River, on the Qujiang River about 6.5 kilometers downstream from the confluence of the Qujiang River and the Lingshan River. The recommended first-phase development and construction project has a catchment area of 10,462 square kilometers above the dam site and an average annual runoff of 11.68 billion cubic meters. The project focuses on power generation, improving the water environment and irrigation conditions, and taking into account the comprehensive development and utilization of shipping.
The project started construction in January 2004. The normal storage level of the reservoir is 40.0 meters and the normal storage capacity is 15.74 million cubic meters. The power station has an installed capacity of 4,500kW×4, with a total installed capacity of 18MW. In September 2006, the first unit was put into operation for power generation, with 4154 hours of power generation per year.
The hydraulic buildings are Grade III projects, the main buildings are Grade 3, and the design and check flood level standards are once in 50 or 100 years.
After the completion of the project, the average power generation for many years can reach 74.78 million kilowatt-hours. At the same time, the water environment and irrigation conditions have been improved, and the comprehensive development and utilization of shipping have been taken into account. Its economic and social benefits are very considerable, and it is also helpful to promote the economic and social development of Longyou County. Has a very important meaning.
The power plant manages production based on the safety production management policy of safety first and prevention first. In April 2015, it was awarded the second-level unit of safety production standardization for rural hydropower stations by Zhejiang Water Resources Department.
Xianhua Reservoir
Xianhua Reservoir is the first BOT project built by the group company, and it is also the largest water conservancy project invested by Pujiang County since the reform and opening up.
Xianhua Reservoir is located about 2km upstream of Jinkengling Reservoir in Pujiang County, Zhejiang Province, and the project is about 6.5km away from Pujiang County. The site is located at the foot of the barrage on the right bank. The site of the inter-basin weir is located on the Huyuan River about 150.0m upstream of Xuexiazhuang Village. Now there are roads leading to the dam site, factory site and weir, and the external traffic is convenient.
Reservoir pivot project consists of a barrage, flood discharge power generation and water diversion structures, trans-basin water diversion structures, power plants and booster stations. The barrage is a concrete face rockfill dam with a maximum height of 74.0m, a crest width of 6m, and a crest length of 190m. The spillway tunnel is a circular pressure tunnel with a length of 255.46 meters. The cross-basin diversion structure adopts a pressureless gate tunnel type, the tunnel is 1776 meters in length, and the power plant adopts diversion ground type and horizontal generator sets. The main workshop and auxiliary workshops are arranged in a shape of "one" along the foot of the mountain; the booster station is equipped with 2 main transformers.
Xianhua Reservoir is a water conservancy and hydropower project that combines water supply and irrigation with power generation. The normal storage level of the reservoir is 238.0m, the total storage capacity of the reservoir is 11.58 million m³, the designed annual water supply volume of the reservoir is 11.68 million m³, the designed irrigation water volume is 2.22 million m³, the installed capacity of the power station is 2×0.5MW, and the annual average power generation capacity is 1.97 million kW.h. The construction of the project makes full use of the local abundant water resources, solves the irrigation water use of Jinkengling Irrigation District including Pujiang County, and meets the comprehensive water needs of Pujiang County and towns and villages for industry and life, and contributes to the improvement of Xianhua Mountain’s provincial-level scenic spots. The development of the environment and cultural tourism in Pujiang plays a very important role in promoting the development of the national economy of Pujiang County.
Pianmahe Level 3 Power Station
The Pianma River Level 3 Hydropower Station in Lushui City, Yunnan Province was fully invested by the group company and was developed and constructed in October 2011. It is located within the Gaoligong Mountain National Nature Reserve in western Yunnan. The minimum distance from the China-Myanmar border is only 43 meters. The river is a tributary of the Irrawaddy water system and flows through Myanmar into the Indian Ocean. The project consists of major buildings such as the first hub, water transfer tunnel, pressure pipeline, power plant, booster station and power transmission line.
The power station is a high-head unregulated radial power station. It mainly undertakes power generation tasks, taking into account factors such as unit operation reliability and flexibility, convenient maintenance and engineering economy. It adopts horizontal units, the number of units is 2, and the single unit capacity is 4000 kilowatts. . After the completion of the project, the average power generation for many years reached 41.48 million kilowatt-hours, and the installed annual utilization hours were 5,185 hours. The project was officially merged into the Nujiang Power Supply Bureau of the Southern Power Grid for power generation in February 2013.
The completion of the project gave full play to and utilized the hydropower resources of the Pianma River, promoted the optimal allocation and sustainable use of water resources in the Pianma River Basin, and also promoted the economic development of the Pianma River Basin. It is also a major investment highlight of the group company in the southwestern border of the motherland.
