Embodiment Construction

[0008] figure 1 Shows a schematic configuration of hydropower device according to the present invention. Hydroelectric apparatus includes an upper tank and a reference numeral 2 denotes the sink by reference numeral 1 indicates, wherein the water level in the basin 1 is located above the water level in the tank 2. Pool 1 and 2 can also be a natural body of water such as a lake or river. 1 and the upper tank and the lower tank connected to water hydropower device 2 further comprises reference numeral 3 denotes a. 3 are arranged in the water turbine indicated by reference numeral 4. Thus, water 3 is divided into two sub-sections. In the upper part 4 of the turbine, i.e. the pressure tube line, reference numeral 31 indicates, and the portion below the turbine, i.e. the suction pipe, reference numeral 32. Turbine impeller 4 includes a turbine, and a guide means for the space surrounding the turbine impeller to be blown, and thus, the turbine impeller can be rotated in a state the air...

Abstract

A hydroelectric power generation device for adjusting the frequency of a power grid, comprising: an upper pool (1); a lower pool (2); a waterway (3) connecting the upper pool (1) to the lower pool (2); a turbine (4), the turbine is arranged in the waterway (3) and the turbine includes an impeller, a guide and a device for supplying air to the wheel space; The asynchronous motor (5) fed; the frequency converter (6) electrically connected with the asynchronous motor (5); the grid transformer (7) connected electrically with the asynchronous motor (5), the frequency converter (6) and the power grid; the resistance ( 8), the resistor is arranged in the DC intermediate circuit of the frequency converter (6), so that the resistor can connect the branches of the DC intermediate circuit to each other; and means for cooling the resistor (8).

Description

Technical field [0001] The present invention relates to a hydropower device for rapid adjustment of the grid frequency and a method for operating such a device for hydroelectric power. Background technique [0002] And the maximum and minimum allowed pressure, only relatively conventional hydropower device slowly, typically up power saving time scale turbine 10 to 30 seconds in the water-based and water column inertia. This is not enough to help regulate the grid frequency in a short time when requirements increase. Therefore, countries such as the UK grid code requirements, specific electric power must be connected to the grid in less than one second depending on the grid frequency or absorbed into the grid, in order to participate remuneration incentives. Inventive content [0003] The present invention solves the technical problem, describes a hydropower device which can adjust the power provided on the indexing time less than 1 second. Further, the present invention is to so...
