Definitions
- the invention relates to a pumped storage power plant, in particular an electrical unit for this, comprising a converter and a rotating electrical synchronous machine, wherein the machine is provided in a cavern.
- renewable energy sources such as wind and solar, provide a steadily increasing share of electricity demand. These energy sources have unsteady operating times. Thus, a direct and permanent supply of consumers with electricity from these sources of energy can not be guaranteed. For this purpose, energy storage must be used, which allow rapid changes between electricity surplus and electricity deficit and their performance and energy flow direction can be changed quickly and continuously.
- energy storage here are different system available, which are particularly suitable for specific amounts of energy and applications cases.
- kinetic accumulators e.g., flywheels
- electrochemical stores batteries, redox flow cells
- electromagnetic stores capacitor, supercapacitors, superconducting coils
- thermodynamic storage tanks compressed air storage tanks, electrothermal storage tanks
- large amounts of energy typically over 100 MWh and usually over 1 GWh pumped storage are used.
- Pumped storage or pumped storage power plants are particularly interesting due to the large amount of energy that can be stored.
- water is pumped from a first natural or artificially created reservoir into a second, higher-lying reservoir.
- the electrical energy is converted into potential energy.
- water from the higher storage tanks are routed via a turbine back to the lower reservoir. Minimizing losses in the conversion processes is particularly important to this system.
- variable-speed drives By decoupling the speed of the machines from a grid frequency, pump and turbine rotational speeds can be adjusted to operate close to optimum efficiency. In addition, it allows the variation of the speed in the pumping mode to freely adjust the power consumption. In particular, variable speed systems can be quickly connected from standstill to the network or synchronized.
- Pumped storage according to the prior art have double-fed asynchronous machines and power electronic frequency converter, whereby a speed control of a pump and a turbine is possible.
- a stator of the double-fed asynchronous machine is connected directly to the power grid with grid frequency.
- a rotor of the doubly fed asynchronous machine is connected to the network via a frequency converter and can thus have a variable frequency.
- a pumping power is controlled and on the other hand, if necessary, the efficiency of the system can be increased.
- pumped storage In pumped storage is often provided that the machinery such as turbines, pumps and motor-generators are housed in an example introduced into a rock cavern, a cavity or in a closed space below the second storage tank.
- Another form of pumped storage provides pump, turbine and motor generator at the lower end of a shaft, with other power plant components are provided, for example, above ground in a building or in the shaft.
- a major disadvantage of this arrangement with double-fed asynchronous is an increased space requirements within the cavern whereby costs for the construction of the pumped storage power plant and excavation of the cavern are significantly increased.
- the transformer has losses of the order of 1-2% of the transmitted active power.
- the use of a transformer is disadvantageous due to the high cost of the transformer.
- a transformer has a significant risk of explosion due to transformer oils and thus represents a significant security risk.
- the present invention has the object to simplify the construction, operation and maintenance of a pumped storage power plant and to increase the efficiency.
- the invention provides an electrical unit for a pumped storage power plant, which can be connected to a power grid.
- the electrical unit comprises at least one frequency converter and a rotating electrical synchronous machine, which serves as a motor or generator depending on an operating mode of the machine.
- the machine can be mechanically connected to a water turbine and a water pump or a reversible pump turbine.
- the converter is designed as a modular multilevel converter MMC and directly or directly, ie without an intermediate transformer, connected to the machine, wherein the converter has an adjustable voltage.
- the converter has a multiplicity of series-connected unit cells for scaling an output voltage.
- the unit cells each have, for example, a capacitor or an inductance,
- unit cells can be controlled separately, for example, to adapt the output voltage to the electrical machine.
- edge steepness and amplitude of pulses between an output of the converter and the machine, for example terminals of the machine to relieve the insulation is limited.
- a multiplicity of voltage steps for example small steps for changing the output voltage, can be used.
- a further embodiment provides that the output voltage has low harmonic distortions so that the mains connection conditions are met without additional filtering and there are no differences in the design of the machine with respect to harmonics compared to a direct mains connection.
- Such network connection conditions are defined, for example, in a grid code.
- the converter is connected to the network side with a block transformer.
- the invention simplifies the construction of a pumped storage power plant, in particular in an underground construction, for example in a rock cavern by saving a transformer between the machine and converter. Continue to be Saves active power losses of the dropping transformer and the electrical unit has an increased efficiency.
- FIG.l a schematic representation of an electrical unit with a converter, a synchronous electrical machine and a block transformer.
- the electrical unit 1 shows a schematic representation of an electrical unit 1 connected to a power network 2.
- the electrical unit 1 comprises a modular multilevel converter 3 and a rotating electrical synchronous machine 4.
- the machine 4 is housed for example in a cavern.
- a block transformer 5 for connecting the electrical unit to the power network 2 is provided in this embodiment.
- Frequency conversion is produced by means of a combination of a rectifier and an inverter, which are connected to one another via a concentrated or distributed voltage intermediate circuit or current intermediate circuit.
- the intermediate circuit furthermore has units for storing energy, for example, capacitors in the case of a voltage intermediate circuit and inductors in a current intermediate circuit.
- the operation of the machine with a freely selectable speed has significant advantages.
- an established, reliable and low-maintenance generator technology can be used.
- a pump and a turbine operate independently of each other in their optimal speed range.
- the operationally accessible speed range extends continuously from zero to the maximum speed and is limited only by the operational limits of the pump and the turbine.
- the pump and the turbine can be combined in principle in a unit, for example a pump turbine.
- Another advantage is a very fast grid coupling and the ability to generate positive and negative reactive power in the converter 3, so that the generator can be operated only with active power, which has a more compact design. Furthermore, can be quickly switched by the use of the converter 3, for example, from pumping to turbine operation.
