Abstract: at present, the construction and operation of small hydropower stations are encountering certain difficulties due to various reasons, such as high construction costs, low electricity prices and poor regulation performance of small hydropower stations, resulting in poor economic benefits after some power stations are completed and put into operation. So is there a way out for small hydropower, can it achieve self-development and achieve a virtuous cycle? The answer is yes, there is a way out

key words: to realize a virtuous cycle of hydropower at present, the construction and operation of small hydropower stations have encountered certain difficulties. The reasons are various, such as high construction costs, low electricity prices, and poor regulation performance of small hydropower stations, resulting in poor economic benefits after some power stations are completed and put into operation. So is there a way out for small hydropower, can it achieve self-development and achieve a virtuous cycle? The answer is yes, there is a way out. (1) First of all, we should establish a management entity for the unified generation, supply and use of small hydropower stations, have their own power supply area, and implement the mechanism of spontaneous, self supply, self use and surplus. In this way, the type III sample is only suitable for measuring the tensile strength of molded chopped glass fiber reinforced plastics, so as to avoid the distance and reduce the transmission loss. After deducting the line loss, the annual average electricity price is only about 0.12 yuan. If the power is supplied by itself, the meter can be read to the household. After deducting the line loss and management fee, about 0.35 ~ 0.5 yuan can still be obtained for each kW · h, that is, 0.25 ~ 0.4 yuan can be charged for each kW · h. In this way, the power station will have vitality and may develop itself. (2) It is necessary to establish a leading reservoir with a small watershed as a unit, so that small hydropower can have self-regulation capacity. Although the storage capacity is small, it is better to continue the construction on the waterproof layer to achieve daily regulation, so that it can store water without power generation at low peak load, and save power generation at peak load. Of course, it would be better to achieve seasonal adjustment. In this way, it can first solve the problem of excess electricity, so that the electricity price of low load (0.06 yuan/kw · h in high water period and 0.07 yuan/kw · h in low water period) becomes the electricity price of peak load of 0.2 yuan/kw · h, with an increase of nearly three times. (3) The hydropower station operates some industries by itself. 6. The key switch is pressed, which has high product value, good sales and large power consumption, so that the surplus of self generated power can still be sold locally, so as to achieve local balance and improve the electricity price of small hydropower. As small hydropower is concentrated in some places, there is surplus electricity except for agriculture, townships (towns) and civil use. It is necessary to do a good job in energy conversion to build some small factories. Jinpangou power station and shiziyan power station in Gucheng County set an example in this regard. They use the electricity they generate to run small factories. Jinpangou power station has set up an oxygen plant, with an annual output value of 140000 yuan and a profit and tax of 20000 yuan; Shiziyan power station has set up a short, small and fast project and a fine wood processing plant jointly established with Xiangyang bearing plant, with an annual output value of 800000 yuan and a profit of 120000 yuan. To increase the income of the unit, we have also arranged surplus personnel. (4) Properly handle the relationship between "taking" and "giving", and coordinate the relationship between small hydropower and finance. The purpose of the financial department in supporting the development of production is to open up financial resources and increase revenue. Give less and get more, and the economic benefit will be high. However, the development of small hydropower is just the opposite, giving more and obtaining less directly. In this regard, the financial department should correctly understand, deal with special cases, give more and take less, and try to increase investment. (5) Strengthen industry management. Small hydropower is under the jurisdiction of the county water resources (hydropower) bureau, with unified planning, construction and dispatching. Management is a comprehensive frontier science. Management is a productive force, and management produces benefits. By strengthening management, an enterprise can turn losses into profits and become vigorous. On the contrary, poor management will make a good enterprise close to bankruptcy and heavily in debt. (6) Strengthen professional technical training and improve the professional quality of operators. Poor benefit of the power station due to poor quality of operators. Therefore, personnel training is a top priority. Various learning classes should be held in various forms to improve the quality of operators and cultivate their ability to analyze, solve and deal with problems, so as to reduce the number of misoperations and accidents and achieve optimal, economic and safe operation. (7) Dredge the channels of bank loans. The electricity price of small and medium-sized hydropower stations must be raised. Only when the new power station implements the new power and new price policy, can the power station have the ability to repay, so as to gain the full trust of the banking sector and make the banking sector dare to lend and be willing to lend; Make every effort to implement the local self raised funds. The construction of small and medium-sized hydropower is the business of local government departments. We must open up new avenues, mobilize forces from all walks of life to raise funds through multiple channels and at multiple levels, establish small and medium-sized hydropower development funds, and use them with compensation. The sources of local self raised funds include the following aspects: ① mobile financial resources of local finance; ② Over - take into energy fund; ③ Electricity maintenance fund; ④ Power construction funds collected according to state regulations; ⑤ Enterprises and individuals invest in joint power supply; ⑥ Sale of electricity rights; ⑦ To issue bonds upon approval; ⑧ The water conservancy utility fee shall be shared for the power stations with flood control and irrigation tasks; ⑨ Implement new electricity and new prices. In order to speed up the development of the power industry, the state stipulates that nationwide, it is mainly necessary to increase the support for scientific research by levying 2 cents per kW of the power construction fund. The electricity supplied by small and medium-sized hydropower stations and large electricity supplied by local power stations is transferred from large electricity to users. This part of the power construction fund is collected from users by the power supply department of large electricity. This money should be returned to the water conservancy (hydropower) bureaus of each county as the special construction fund for small hydropower stations. In hydropower construction, it is very necessary for the state to give appropriate support. However, state support includes giving preferential policies and investing certain funds. We should make good use of the past preferential policies. In the past, it was a free subsidy to disburse the small hydropower subsidy funds in the farmland and water conservancy business expenses. Now, it is paid to use the working capital instead of achieving the paid purpose. Therefore, it is suggested that the relevant departments at higher levels should formulate practical measures and management methods to increase appropriation subsidies. Opening up capital channels is the only way to speed up the construction of small and medium-sized hydropower. As long as we use our brains to raise funds, make full use of the national power policy, broaden our thinking and find more channels. With the continuous development of the national economy, it is entirely possible to take advantage of the great opportunity of the state to set up small and medium-sized hydropower to find a new way for small hydropower to survive and develop and realize a virtuous cycle of small hydropower
