Description

{BARGE STRUCTURE OF A BARGE MOUNTED POWER GENERATION PLANT}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a floating power generation plant, and more particularly, to a barge line of a floating power generation plant capable of stable power generation work by changing a cross-sectional shape of a barge main body to which a plurality of power generation units are installed.

Typical power generation methods include hydroelectric power plants, thermal power plants, and nuclear power plants. These power generation methods require large-scale power generation facilities and sites, and in particular, Environmental problems.

On the other hand, the power reserve ratio is a figure that shows how much more electricity can be supplied than electricity currently used. If the number is high, the electricity supply can be used with sufficient electricity, but if it is low, Lt; / RTI >

Since the power can not be stored, if the value is too high, it is necessary to maintain an appropriate level because it causes an economic loss such as wasting energy and burdening the electric charge, and it is proper to maintain the electric power retention rate of about 15% .

Nevertheless, it is predicted that electricity demand will surge and power reserve ratio can not be maintained at an appropriate level, or electricity supply and demand may not be smooth, and measures to actively cope with such power crisis situation are serious have.

As part of this plan, a new concept plant for manufacturing a combined-cycle thermal power plant on a barge is to produce finished products of a combined thermal power plant at the shipyard and install it on a barge, A barge-mounted power plant (BMPP) is attracting attention as an alternative.

As such, BMPP has a shorter production period of one year and three months (excluding purchasing, design, and shipping periods) compared to a combined cycle power plant, which requires an average construction time of 4 years or more on the land, In addition, land acquisition and transmission line construction is not required separately, which not only makes it possible to reduce costs, but also has the advantage that it can be easily expanded.

The facility capacity of BMPP reaches 200MW, which corresponds to 20% of nuclear power generation (1,000MW capacity per unit), and it can be resiliently operated according to power demand, which is considered as a solution for the power crisis.

The BMPP currently being developed in Venezuela has the largest capacity of 340MW, but it can improve quality and delivery time compared to construction of overseas offshore power plant, which is difficult to supply construction equipment and high-level construction manpower. In addition, After finishing the production, it will be transported to the site of the power plant and installed and run on site.

In addition, since the plant is being manufactured, it can be flexibly operated in Southeast Asia such as Myanmar and Angola, where it is difficult to connect the national grid.

In addition, when mobility is utilized, the old power plant can be discarded due to aging, etc., and replaced with short-term power vacancies in constructing a new plant.

In addition, it is free from the opposition of local residents and the risk of terrorism as compared with the construction of the land power plant, and it can solve the gap of power supply that generally occurs when replacing the old power plant, and the construction regulations of the power plant It is expected to be used in advanced countries.

1 is a conceptual diagram showing a conventional BMPP.

Referring to FIG. 1, a conventional BMPP includes a power generator 10, which is composed of a turbine 4 and a generator 6, on a foundation 2 on a barge of a general type. And is configured to connect the turbine 4 and the generator 6 to the shaft 8. [

The steam generated by the fuel stored on the barge is used to rotate the turbine 4 using the steam so that the rotational force of the turbine 4 is transmitted to the generator 6 through the shaft 8, 6 are driven, they produce electricity.

The foundation 2 of the barge line is fitted with a pile 12 which can be fixed to the underside so that the barge line is not affected by the surrounding environment of the sea, for example wind and waves.

However, in the conventional BMPP, hogging and sagging due to a bending moment occur during floating operation. Therefore, it is possible to assume a problem that is critical to the operation of the power generation apparatus have.

That is, since the floating barge is operated in the sea, when the unbalanced load is applied to the wave load in the floating state, the longitudinal moment of the float generates tensile force in the upper part of the hull and compressive force in the lower part The central portion of the float may be deformed as if lifted up.

Therefore, the conventional BMPP causes a phase difference between the generator 4 and the turbine 6 as the center portion of the foundation 2 is lifted up as shown in Fig. 2, depending on various marine conditions, (8) may be deformed or broken.

Further, since the shaft 8 of the power generating apparatus 10 used in the current BMPP is mostly made for land use, it can be assumed that it is difficult to apply it for marine use.

And the strength increasing portion is installed to be symmetrical to the lower portion of the barge main body to which each of the power generating units is installed.

And a semi-circular groove or a quadrangular quadrilateral groove is formed between the strength increasing portions.

And the thickness of the barge main body having the strength increasing portion is greater than the thickness of the barge main body therebetween.

And the water surface of the seawater is positioned at the center of gravity of the barge main body.

The power generation unit may include a first power generation unit composed of a gas generator and a turbine, and a second power generation unit composed of a steam generator and a turbine.

The first power generation unit and the second power generation unit are symmetrical about a vertical center line.
