Definitions
- Converter cell module voltage source converter system comprising such a module and a method for controlling such a system.
- the invention relates to a converter cell module and a voltage source converter system comprising such a module.
- the converter cell module according to the invention comprises at least two switching elements, means for energy storage and an autotransformer .
- the autotransformer is arranged to bypass the converter cell module in the case of failure occurring in the converter cell module.
- the invention further relates to a method for controlling such a system.
- Chain-link Multi-level Voltage source converter systems comprise a number of converter cell modules connected in series. Each converter cell module forms one "link" (or cell) of a single phase voltage source converter (VSC) and is switched on/off a number of times during a fundamental frequency cycle of an ac system.
- the chain-link converter may comprise a number of phases, each phase comprising a chain of such converter cell modules connected in series to each other.
- the converter cell typically comprises semiconductor assemblies of turn-off type, e.g. insulated gate bipolar transistors (IGBTs) .
- IGBTs insulated gate bipolar transistors
- a converter cell module comprises four IGBTs.
- a free-wheeling diode, also denoted anti-parallel diode, is connected in parallel with each IGBT and conducts in the opposite direction of the IGBT.
- the IGBTs are connected in an H-bridge arrangement with a DC link capacitor bank.
- the number of converter cell modules connected in series for each phase is proportional to the AC voltage rating of the ac system.
- the number of converter cell modules can therefore be large for high voltage applications having no mains transformers, which entails high costs.
- the current demands on the converter cell modules may also be low in high voltage systems, resulting in the use of overrated semiconductor components, which again entails high costs .
- the series connected cells have a feature that allows the cell to be bypassed in case of a failure in the cell in order to enable continuous operation of the converter system without tripping if for example a semiconductor device fails. That is, if the semiconductor device, e.g. the IGBT, is damaged the cell cannot be allowed to go into an open circuit, as the series-connection of converter cell modules then would form an open circuit.
- semiconductor devices available that go into short circuit when damaged, e.g. press-pack IGBTs, which if broken become a short-circuit, a behaviour that is known as short- circuit failure mode (SCFM) .
- SCFM short- circuit failure mode
- the cost of such semiconductor devices is very high, even as large as twice the cost of standard industrial type of devices.
- a converter cell module for a voltage source converter system comprises at least two switching elements, means for energy storage and an autotransformer .
- the autotransformer is arranged to bypass the converter cell module in the case of failure occurring in the converter cell module. By such an arrangement is the failed module bypassed by the autotransformer, in the case of any failure in the converter cell module, thereby not causing any operational stop when used in a voltage source converter system.
- the at least two switching elements connected in parallel.
- Each having at least two semiconductor assemblies being of turn off type and connected in series, and each semiconductor assembly having a rectifying element connected in antiparallel .
- Each of said converter cell modules comprises further at least one means for energy storage connected in parallel with said switching elements.
- the means for energy storage comprises for example a capacitor.
- each of the semiconductor assemblies an insulated gate bipolar transistor (IGBT) .
- the autotransformer arranged to provide an inductance to the converter cell module.
- the converter cell module further means for disconnecting the module. Thereby can the converter cell module be electrically disconnected from any other electrical equipment when used in an electrical system.
- a voltage source converter system provided. The system comprises one or more phases, each of said phases comprising at least two converter cell modules as claimed in any of claims 1-5. Bypassing the converter cell modules in the case of failure is performed during continuous operation of said system.
- In another embodiment comprises the system three phases (Ll, L2, L3) . In yet another embodiment are the three phases (Ll, L2, L3) connected in a delta configuration.
- the three phases (Ll, L2, L3) be connected in a Y configuration.
- the system comprises one or more phases, each of the phases comprising at least two converter cell modules.
- the method comprises bypassing the converter cell module or modules in which failure has occurred.
- Figure 1 illustrates a converter cell module in accordance with the present invention.
- Figure 2 illustrates a voltage source converter system in accordance with the present invention.
- Figure 3 illustrates the system arranged in a delta connected arrangement.
- Figure 1 illustrates a converter cell module 3 comprising four IGBT: s (4, 5, 6, 7) connected in a H-bridge configuration where each semiconductor assembly has a rectifying element 9 connected in antiparallel .
- the converter cell module 3 also comprises a capacitor 8.
- an autotransformer 2 is connected such that the converter cell module will be bypassed automatically in the case of failure in the module. In the case of failure in any of the IGBT's, current I will flow as indicated thereby bypassing the module 3.
- FIG. 2 illustrates a voltage source converter system 1.
- a plurality of converter cell modules 3 are connected in series. If a failure occurs in one, or several of the converter cell modules 3, that module, or each of those modules, is/are bypassed by the connection of the autotransformer (s) 2. After bypassing the defect module, or modules, the defect module (-s) may be disconnected from the rest of the converter system by disconnecting means (not shown) .
- Each of the modules 3 are provided with separate disconnectors to allow disconnecting of a single module. Due to the bypassing function provided by the autotransformers 2, no current flows in the defect module (-s) and a cheap and robust standard disconnector may be used.
- Figure 3 illustrates a three phase converter system 1 arranged in a delta connected arrangement. For each phase, a plurality of converter cell modules 3 are connected in series to each other. The number of series connected modules 3 depends on the voltage level of the converter system. The system may also be connected in a Y configuration.
