A.Why choose theme:

- Energy industry is one of the key economic sectors and of every individual country. Background modern production can only be developed through the existence of the energy sector.
- In Viet Nam, many hydroelectric plants were built across the country from north to south such as the Hoa Binh hydropower plant, Thac Ba hydro power plant, hydro power Xe Xan, Tri An hydro-electric plant ... Particular, the Hoa Binh hydropower plant is the largest hydropower plant in Southeast Asia today.
- Operation of the Hoa Binh hydropower plant with 500kV line current was most contribute to improving the stability, safety and economic power system, creating better conditions for economic development, service life people, promoting the process of industrialization and modernization of the country.
- I am extremely proud and proud for the country you have hydro power century: Hoa Binh hydropower plant. Whether going away, but about every home I never forget to remind the Hoa Binh hydropower plant. So I chose this topic in the hope more people know to Hoa Binh Hydroelectric-my pride. 


B. STOCK MENU.
I. Some concepts are related:
1. Hydroelectric plants.
- Hydro-electric power plant is one where the conversion of water energy into electric energy.
- Electric power from hydroelectric power plants is a form of renewable energy, clean energy because the gas emissions that are harmful to the environment as other power plants.
2. How to activities of Hydroelectric.
- Water is convergence from dams with a large potential. Through a system of pipes, the flow of energy is transmitted to the turbine, the turbine is connected to a generator, where they are converted into electric energy.
II. Historical construction of Hoa Binh hydroelectric plant.
- Hoa Binh hydroelectric plant was built at Lake Hoa Binh, Hoa Binh province, on the Da river in northern Vietnam.
- The construction of Hoa Binh hydropower plant is the notable landmarks follows:
+ Peace hydroelectric power plant on the Da River is starting construction on June 11, 1979.
. Prevent Da River stage 1: on January 12, 1983
. Prevent Black River stage 2: on January 9, 1986
+ Time to the first machine (machine 1) Republic National Grid: on December 31, 1988
+ Time machine to the final (May 8) Republic National Grid: on 04/04/1994
- On December 20, 1994 Hoa Binh hydroelectric plant was inaugurated in the joy of the whole nation rejoice.
- This is the received enormous assistance of the Party, State and Soviet experts. During construction has a lot of Soviet specialists and workers Vietnam fell down.
Hoa Binh hydropower plant is a symbol of friendship beautiful high-Soviet Vietnam.
- On December 20, 1994 Hoa Binh hydroelectric plant was inaugurated in the joy of the whole nation rejoice.
III. The specification.
- Design capacity: 1920 MW
- Number of units: 8
The major construction and major construction and installation volume:
1. Reservoir:
2. Hoa Binh hydro power plants.
3.The other works:
IV. The mission of Hoa Binh hydroelectric plant.
1.Duties flood:
Duties of the Red River waterway, flood disaster mitigation for the plains and north of the capital Hanoi. This is the first task of Hoa Binh hydroelectric plant.
2. Task generator:
Hoa Binh hydro power is the power The main power system in Vietnam. 8 factory units with installed capacity of 1920 MW. Design each year to provide 8.16 billion kWh of electricity to the national economy.
3. Duties irrigation, agriculture against term:
This operation of hydroelectric peace contributed regulate water resources, irrigation performing their duties, against limited to agriculture.
4. Waterway:
The presence of a hydroelectric power plant Peace contribute significantly improved the travel and transportation by waterway traffic in both upstream and downstream.
V. Some achievements have been achieved.
- From when the first units put into operation as of August 15, 2007, the Hoa Binh hydropower produced approximately 120 billion kWh of electricity, including transmission in Central and South about 20 billion KWh.
- Alone in 2004: Production of electricity produced by the plant has reached 8.406 billion kWh, an increase of 103.75% over plan

- 2007 output power with the largest number ever: output date is September 9, 2007 High: reaching 47.749 million KWh; May has the highest output power in September 2007: reached 1.382 billion KWh, you play the highest output power is achieved III/2007 you: 3.8 billion kWh and this year with plans by the Electricity of Vietnam to the year of 7.7 billion KWh, but the company is expected to end of the year will reach 9 billion KWh electricity.
- In addition, the presence of the Hoa Binh hydro power created by the regular waterway online Hai Phong - Ha Noi - Hoa Binh - Son La, the largest contribution to the development of social and economic life of people of the Northwest.
- Every year, the program has cut average of 4-6 large floods, with a flow cut from 10000-22650 m3 / s.
ACHIEVEMENT AWARDS HAS BEEN:
With excellent performance, Hoa Binh hydro power plant has been peaceful State of Vietnam awarded the titles:


- Labor Medal first class, second, third.
- 24 Second-Class Labor Medal, three for units and individuals under.
- 05 The flow of the Government flags.
- The flow of 02 flags General Confederation of Labor Vietnam.
- 02 Cup Silver Vietnam quality.
Many, in peasie of the ministries, all levels, sectors and provinces of Hoa Binh.
VI. Some of the difficulties encountered
- Weather, natural change complex.
- National Grid system lacks serious.
- Over time a number of long-term operation of equipment and machinery of the plant has been degraded and damaged.
C. Conclusions:
1. Hoa Binh hydroelectric plant was built and completed in 15 years (1979-1994) and has become a symbol of friendship beautiful high-Soviet Vietnam.
2. Hoa Binh hydropower undertook four important tasks are: flood control, power generation, water supply for agricultural production, industrial and social, while ensuring water transport.
3. After 20 years went into operation in Hoa Binh hydro power plants have contributed to the large on the economic development of the country, excellent complete assigned tasks.
4. Hoa Binh hydroelectric plant has been awarded many certificates of merit, medals of Labor Party, the State of Vietnam awarded.
In the process of implementing to finance, limited by time, the ability to research resources and physical facilities should not prevent others from those exist. However, through the research topic I acquired a lot of things useful. Limitations of the topic, so I hope to receive contributions from teachers and subjects you to be longer.
