December 28, 2022. The groundbreaking ceremony of the 2 × 660,000 kilowatt Pannan power generation project of Panzhou City using low-calorific value coal resources was held in the industrial park of Pannan on the afternoon of December 28, 2022. The project has a total investment of 5.507 billion yuan and is an important part of the overall energy core component of Liupanshui. It is planned to build two 660,000 kilowatt high-efficiency ultra-supercritical CFB production units, using low-calorific value coal such as peat and gangue produced in the Panzhou mining area as the main fuel. 3.6 million tonnes.

Shannipo Hydropower Station is located in Shunchang Township, Shuicheng County, Liupanshui City, Guizhou Province, in the middle of the main stream of the Beipan River. It does 118 km (rou mileagetier, the same. below) from Shuicheng and 362 km from Guiyang. Near the project area are Provincial Road 217 and County Road 230 (Shuipan East Expressway) which cross the river, making external transportation very convenient. Once arrived in Guiyang (or Shuicheng), the equipment can be transported by road to the power plant construction site.

According to the Guizhou provincial power system plan, this power plant will be connected to the Guizhou power system to operate after it is put into operation. After the power plant is integrated into the power grid, it must be connected to the power grid of Guizhou province. participate in the regulation of peaks of the system and try to envisage the complete energy production of the unit during the rainy season. The role of the Shannipo hydroelectric power station in the system is as follows: during the dry season, it is mainlyent intended for peak load; during the flood season, it is mainly for base load and face load;

The power plant consists of a dam, a dam flood evacuation system, a water diversion system from the right bank, a pressure regulating well and an underground power station. The power plant is a medium-sized third-class project, the dam is a class 2 building, and the water diversion and power generation system is a class 3 building.

This power plant has an installed capacity of 2×90 MW. It is a medium-sized power station and has an underground power station with water diversion on the right bank. The water diversion system is arranged in the form of "a hole, a well, a pipe and two machines", that is, water is supplied from the socket of water through a diversion tunnel to the wells of pressure regulation after the pressure regulation well. , it passes through a main pressure steel pipe and two branch pressure steel pipes in front of the factory. Connect two hydrogenerator units respectively, then discharge them into the downstream river through their respective leakage pipes. The inner diameter of the diversion tunnel is 8m, the length of the diversion tunnel is about 2496.83m, the pressure regulating chamber is impedance type, the inner diameter is 23m, and the height is of 70 m. The pressure regulating chamber is connected behind the pressure steel pipe with a diameter of 6.7 m and a total length of approximately 110 m. The diameter of the branch pipe after the branch is 3.95 m. Two vertical shaft Francis hydrogenerator units with one. a single unit capacity of 90 MW is installed. The longest unit branch pipe is approximately 48 m. The designed flow of the cenelectric trale is 209 cubic meters/second and the throughput of a single machine is 104.5 cubic meters/second. The average water consumption of the power plant for electricity production over the years is 3.111 billion cubic meters.

Shannipo Hydropower Station is a diversion type power station. To ensure environmentally friendly flow, the diversion tunnel is opened and connected with a pressurized steel pipe to divert water. A small 5.5 MW hydroelectric generator is installed. on the right bank about 400m behind the dam. It is planned that the foundations of the unit (large unit) will be laid in September 2012; the first unit (large unit) will be commissioned on December 30, 2013; in March 2014, race. The first large unit of the small machine was put into operation later.

This power plant is a third-class and medium-sized project. The maximum height of the baserrange is 119.40 m. The static investment of the project is 1.520 billion yuan, and the total investment is 1.692 billion yuan. The project is expected to be commissioned in September 2013.
