A voltage source converter includes first and second DC terminals which have at least one converter limb extending therebetween. Each limb portion includes a chain-link converter that extends between an associated AC terminal and a corresponding one of the first or the second DC terminal. Each chain-link converter also includes a chain-link converter controller which is programmed to control a series of connected chain-link modules. The voltage source converter additionally includes a voltage source converter controller which is arranged in operative communication with each chain-link converter controller to coordinate operation of the chain-link converters. Each chain-link converter controller is further programmed to reconstruct from a received modulation index demand the chain-link converter voltage reference, which the chain-link converter it is controlling is required to produce, by multiplying the received modulation index demand by a total voltage sum established at a first time instant.

Voltage source converters for power conversion in a HVDC power transmission network

An electrical assembly including a converter for connection to an electrical network, the converter including at least one module having at least one switching element and at least one energy storage device, the switching element and the energy storage device arranged to be combinable to provide a voltage source, the electrical assembly including a controller configured to control the switching of the switching element, wherein the electrical assembly includes a sensor configured for measuring a current of the electrical network, wherein the controller and sensor are configured to carry out a characterization of an electrical parameter so that, in use the controller controls the switching of the switching element to modify an electrical parameter of the converter so as to modify the current of the electrical network, the sensor measures a resultant modified current, and the controller processes the measured resultant modified current to characterize the electrical parameter.

Electrical assembly having a characterized electrical parameter

There is provided a switching valve for a voltage source converter, the switching valve including a number of modules, each module including at least one switching element and at least one energy storage device, the or each switching element and the or each energy storage device in each module arranged to be combinable to selectively provide a voltage source, the switching valve including a controller programmed to selectively control the switching of the switching elements to select one or more of the modules to contribute a or a respective voltage to a switching valve voltage.
