Definitions

  • the invention relates to a method for regulating a power converter, in which a setpoint of a control parameter is limited by at least one limiting value.
  • the converter In many energy transmission applications, for example in a high-voltage direct current transmission system (HVDC system), especially when using IGBT-based VSC technology (e.g. modular multi-stage converters), the converter is a thermally sensitive component. Even short-term overloads (in the ⁇ ls range) of semiconductors or semiconductor switches installed in them can result in destruction of the converter with high economic costs. At the same time, high demands are placed on the converter with regard to its short-term overload capability. This generally leads to a costly oversized converter design.

  • the control of the converters is adapted in the known converter systems.
  • the adaptation includes a limitation of the setpoint of one or more of the control parameters.
  • the usually several setpoints for the converter control are usually specified by a higher-level control system. So far, the setpoint has been limited on the basis of permanently stored characteristic or limit values.
  • the limit values are mostly derived from calculations of stationary operating points of the converter system.

  • the dynamic performance of the converter can be increased without an increase in its overall costs.
  • the method according to the invention allows the Converter in the event of brief overloads and at the same time avoids shutdowns through higher-level protective devices. In this way, particularly expensive transmission failures can be prevented.
  • in stationary operation of the converter under suitable circumstances (eg at low outside temperatures and a higher power of a cooling system of the converter), increased transmission or reactive power is made possible.
  • the converter temperature is a semiconductor temperature of a semiconductor switch of the converter.

Additionally or alternatively, for example, an average capacitor voltage of all capacitors of a converter branch can also be used as measurement parameters for the temperature model.
  • a modular multi-stage converter is a live converter which is characterized by a modular structure. In each converter branch, the multi-stage converter comprises a series connection of two-pole switching modules. Each switching module comprises several semiconductor switches and an energy store, usually in the form of a capacitor.
  • the semiconductor switches can be controlled independently of one another, so that a switching module voltage is connected to the connections of the respective switching module. is adjustable. Examples of switching module topologies are the half-bridge and full-bridge switching modules known to the person skilled in the art.
  • the method according to the invention is particularly advantageous for the operation of a modular multistage converter, because an oversizing in the design of the multistage converter can be avoided.

If several limit values are defined for several control parameters at the same time, this creates a multidimensional problem with mutually dependent variables, because the different control parameters may not be limited independently of one another. At the same time, despite the interdependencies, one or more degrees of freedom remain when determining the limit values.
  • This Degrees of freedom can be used to select the individual limit values according to the requirements for the converter system or for energy transmission according to a priority. This selection process can also be referred to as prioritization. For example, in a dynamic overload case, reactive and active power of the converter system can be limited, for example, based on a current requirement profile.

  • control device is set up to limit a setpoint value of a control parameter by at least one limiting value which is determined or can be determined dynamically as a function of a converter temperature.
  • the converter is preferably a modular multistage converter. It is known that modular multistage converters are particularly complex, and their internal variables (such as the semiconductor temperature, for example) change over time largely independently of their external variables (current, voltage, reactive power). A static limitation of the External sizes can therefore not guarantee comprehensive protection against thermal overloading of the converter or its semiconductor. For this reason, the advantages of the solution according to the invention of the time-dynamic, temperature-dependent setpoint limitation are particularly apparent in connection with a modular multi-stage converter.
