<P>PROBLEM TO BE SOLVED: To provide an inverter for a coordinating system which does not stop operation, when an abrupt voltage drop occurs in a power system. <P>SOLUTION: The inverter 3 for the coordinating system, which coordinates a distributed power supply 2 for outputting DC power with the power system, includes an inverter body 4 for converting the DC power of the distributed power supply 2 to AC power to be output to the power system, and a controller 7 for controlling the inverter body 4. The controller 7 has a function to control the inverter body so that the overcurrent generated by an abrupt voltage drop such as the instantaneous voltage drop in the power system becomes lower than a prescribed setting value, also to control the inverter body so as to restrict the power output from the inverter body 4 according to a degree of reduction in the system voltage in the voltage reduction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
