摘要： Segmenting a power distribution network comprising AC power generating stations synchronously interconnected by AC power transmission paths. The stations operate within market sectors and are subject to market rules. The method includes identifying all transmission paths which extend between differing ones of the sectors and segmenting the path by inserting a controllable DC link in the path. Each of the sectors is then operated asynchronously. Power flow and counter-flow between the sectors is controlled by controlling the DC links. A power transmission network is disclosed comprising AC power generating stations operable within market sectors subject to market rules; power transmission paths interconnecting the stations, at least some of the paths extending between differing ones of the sectors, including a controllable DC link in the path for desynchronizing the differing sectors; and, control means operatively connectable to each of the DC links for controlling power flow between the differing sectors.

摘要： A method of segmenting a power distribution network which comprises a plurality of AC power generating stations synchronously interconnected by AC power transmission paths is disclosed. The stations operate within associated market sectors and are subject to associated market rules.

Each of the sectors is then operated asynchronously. Power flow and counter-flow between the sectors is controlled by controlling the DC links. As well there is disclosed a power transmission network which comprises a plurality of AC power generating stations operable within associated market sectors subject to associated market rules; power transmission paths interconnecting the stations, at least some of the paths extending between differing ones of the sectors; and wherein each of the paths which extend between differing ones of the sectors includes a controllable DC link in the path for desynchronizing the differing sectors; and, control means operatively connectable to each of the DC links for controlling power flow between the differing sectors.

摘要： A static converter includes a current converter on the three-phase side and a current converter on the single-phase side, which are electrically conductively linked to one another on the DC voltage side, and which are respectively electrically conductively connected on the AC voltage side to a feeding three-phase network and a single-phase receiving network. According to an embodiment of the invention, one network-commutated current converter is provided as the current converter on the three-phase side, wherein the current converter on the single-phase side has two phase modules which are connected in parallel on the DC voltage side and whose current converter branches each have at least one two-pole subsystem. This results in a static converter which is simpler and costs less than a known static converter.

摘要： An electrical interconnection system (100) comprises a variable frequency rotary transformer (201) and a control system (104). The control system (104) adjusts an angular position of the rotary transformer (102) so that measured power (P1) transferred from a first electrical system (22) to a second electrical system (24) matches an inputted order power signal (P0). The controller limits the power requested by the power order signal based on measured voltages, e.g., the controller has a power-limit function which overrides the order power signal when a measured power exceeds a limit computed from the measured voltages. The limit function is a fraction of maximum theoretical power.
