    General information To assess the inverter system required, the following distinction can be made between the types of power generation: ● Power generation with rotating machines ● Power generation without rotating machines In particular, the amount of power generated depends largely on fluctuating ambient conditions, such as wind speed or exposure to sunlight.

  • Page 21: Grid Types

    Grid types Power grid A power grid covers a wide area, is generally supraregional and comprises large power generating units (regarding the electric power). It is operated by a power supply utility, which is responsible for the grid, and therefore also grid codes. Generating units, which feed into a power grid must synchronize their voltage and frequency to that of the power grid.
  • Page 22 Grid types 3.1 Power grid Function modules for the power grid When operating a generating unit connected to a power grid, a power utility company can specify grid codes. Software functions are required to fulfill the requirements resulting from grid codes. These are defined in function modules, and must be explicitly activated. The following function modules of the Active Line Module are typically required to satisfy the requirements arising from grid codes: ●...

  • Page 23: Island Grid

    Grid types 3.2 Island grid Island grid An island grid supplies a limited area and has no connection to the public grid or to other grids. The utility company operating the grid must maintain the balance between used and generated power in the island grid; an energy storage system can be used. The company operating an island grid can define their own grid codes.

  • Page 24: Microgrid

    Grid types 3.3 Microgrid Microgrid A micro grid represents a locally constrained electrical system with several power generating units, loads and possibly energy storage systems. This can be connected to a large power grid – or can also be independently operated (i.e. an island grid with one or several power generating units).

  • Page 25: Standards And Directives

    Standards and directives When feeding electric power into a grid, different requirements can apply depending on the actual location. Frequently, the requirements depend on the particular country, and in some cases depend on the specific guidelines (grid codes) of the individual power utility company. This is complemented by the individual conditions resulting from the power generating application itself.

    Function modules The function modules, which are required to feed power into an island grid or micro grid – or to fulfill the grid code requirements of a power grid – are described in this chapter. Overview Power and island grids have different requirements relating to the open-loop and closed-loop control for grid infeeds.
  • Page 30 Function modules 5.1 Overview ● Function module for grid droop control The "Grid droop control" function module enables an island grid to be created. The inverter for feeding into the grid has the task of controlling the frequency and the voltage in the grid, and assumes an "grid former function".
  • Page 31 Function modules 5.1 Overview ● Function module dynamic grid support The "Dynamic grid support" function module allows grid faults to be ridden through and allows grid-supporting reactive currents to be injected; this is specified in many grid codes in order to clear short-circuits. Contrary to line droop operation for island grids, in this particular case, the Active Line Module is operated as grid support element with DC link voltage and grid current control.

    Function modules 5.3 Description of the function modules NOTICE Damage to other grid components as a result of overvoltage Without using additional monitoring functions, the dynamic grid support can mean that even when a subgrid is completely isolated from the power grid (unintentional creation of an island grid), PWM/pulsed operation of the Active Line module in the disconnected subgrid is maintained.

  • Page 44: Voltage-Time Monitoring

    Function modules 5.3 Description of the function modules Function As the grid control is missing, generally the creation of an island grid quickly results in violation of the frequency and voltage limit values. As a consequence, it is detected by the frequency and voltage monitoring function.

    Detailed descriptions of the function modules 6.1 Additional closed-loop controls for current-controlled operation Figure 6-1 Additional modules for current-controlled operation 6.1.2 Dynamic grid support Background A parameterizable characteristic allows a reactive current to be specified corresponding to the deviation of the grid voltage from its rated value. This is specified in many grid codes. The background to this requirement is the inductive behavior of a grid inverter, whose most simple equivalent circuit diagram comprises a series circuit of a controlled voltage source and inductance L.
  • Page 51 Detailed descriptions of the function modules 6.1 Additional closed-loop controls for current-controlled operation Conversely, a reactive current results in a voltage change at inverter outputs u12, u23. The characteristic is selected so that the line voltage change is counteracted, therefore helping to stabilize the grid voltage (inverter acts as grid support element).

    Detailed descriptions of the function modules 6.1 Additional closed-loop controls for current-controlled operation In most applications, a setpoint other than zero does not make sense. During an FRT, a possibly required non-symmetrical support current is directly injected internally (p5509[8]). In the default setting of the dynamic grid support with p5500.3 = 1, the negative sequence system control is automatically activated, in order to guarantee current symmetry even for 2- phase grid faults.
