Description

{BARGE MOUNTED POWER GENERATION PLANT}

The present invention relates to a floating power generation plant, more particularly, to a floating power generation plant capable of separating a barge main body from a foundation on which a power generating device is mounted,

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, the BMPP is shorter than the combined cycle power plant, which requires an average construction time of more than 4 years on the land, and the pure production period is about 1 year and 3 months (excluding purchasing, designing and transportation period) 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 capacity of BMPP reaches 200MW, which is equivalent to 20% of nuclear power generation (1,000MW capacity per unit), and it can be resiliently operated according to electric power demand.

Currently, BMPP, which is installed in Venezuela, has the largest capacity of 340MW. However, it can improve the quality and delivery time compared to the construction of overseas offshore power plant, which is difficult to supply construction equipment and high-level construction manpower. After the plant is finished, 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.

It is not searched in the patent literature relating to BMPP as prior art which is a background technique of design.

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 to 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 the bending moment occur during the floating operation, and thus it is possible to assume a serious problem in 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 can be deformed as if lifted up.

Therefore, the conventional BMPP can cause the 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 according to various resolutions, 8) may be deformed or broken.

In addition, since the shaft 8 of the power generating apparatus 10 used in the current BMPP is mostly made for land use, it is possible to assume a lot of difficulties in applying it to marine applications in consideration of deformation of the shaft as described above.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a barge for a barge and a foundation in which a power generator is mounted, The present invention provides a floating power generation plant capable of absorbing deformation of a foundation by a compressive force and capable of stable power generation work even in a poor marine environment regardless of a foundation deformation.

According to an aspect of the present invention, there is provided a floating power generation plant comprising: a barge main body suspended in the sea; A foundation installed at an upper portion of the barge main body so as to install a power generation unit; And an elastic body interposed between the barge main body and the foundation.

The barge main body is formed with a hollow portion, and the foundation is a plate installed on the hollow portion so as to be separated from the barge main body.

The elastic body may be a plurality of elastic springs, and each of the elastic springs may be mounted between the barge main body and the foundation at equal intervals relative to the center of gravity of the foundation in which the power generating unit is installed.

A lateral movement preventing cushion of the foundation may be attached to the front, rear, left and right sides of the hollow portion.

The power generation unit may include a plurality of power generation units installed at regular intervals with respect to the center of gravity of the foundation.

At this time, any one of the plurality of power generation units may be constituted by a gas generator and a turbine, the other power generation unit may be constituted by a steam generator and a turbine, or a combination thereof.

According to the embodiment of the present invention, since the barge main body and the foundation are separated and separated by the elastic body, even if the barge main body is deformed by the wave load, the foundation of the power generator is absorbed in its deformation, So that the vibration problem is solved.

Further, according to the embodiment of the present invention, there is no need to develop a separate shaft of the power generator for marine use, and it has an effect of widening the operational restriction range according to the marine environment.
