摘要： An electrical energy supply system comprises at least one asynchronous generator (101) and a converter system (102) connected to the electrical terminals of the asynchronous generator. The converter system is configured to convert the voltages of the asynchronous generator into voltages suitable for an external system to be supplied by the electrical energy supply system. The electrical energy supply system further comprises capacitors (103) connected to the electrical terminals of the asynchronous generator at least during starting of the asynchronous generator. The capacitors are suitable for exciting the asynchronous generator during the starting. Thus, there is no need for a control arrangement for controlling the converter system to excite the asynchronous generator during the starting.

摘要： Method and arrangement for connecting an AC electric motor (M 1 , M 2 , ... M N ) to an AC electricity network (L) in a system which comprises a frequency converter (FC), with which the motor is started, and contactors (S 11 , S 12 , S 21 , S 22 , S N1 , S N2 ), in which method the supply source is changed by means of the contactors from the frequency converter to a direct network supply, in which method the frequency converter is stopped before changing the supply source, and in which method in connection with changing the supply source the control of the contactors is started before stopping the frequency converter.

摘要： Method and apparatus for measuring an earth fault current in an output circuit of an inverter (INU) operating on the PWM principle and forming alternating-current voltage from direct-current voltage, the output currents (i U , i V and i W ) of which inverter are measured, and which inverter comprises at least two phase switches implemented with power semiconductor components (V 1 - V 6 , D 1 - D 6 ), which switches, controlled by a control unit, connect their own output phases to a positive (+) pole and to a negative (-) pole of a direct-current voltage source such that the phase switches are repeatedly both in different positions and also in the same positions, wherein the results of current measurement during two opposite switch position combinations are recorded in memory, and the earth fault current is calculated by forming a difference of the measurement results of said combinations.

摘要： Method for synchronizing inverter units (INU11, INU12) that are connected in parallel and supply a motor, and a parallel connection arrangement, in which motor is either one winding, which is supplied by inverter units connected in parallel, or a plurality of parallel windings, in which each winding is supplied by its own inverter unit, in which parallel connection one inverter unit functions as a master and the others as slaves, in which method a telecommunications bus is arranged- between the units, and in which each inverter unit has its own modulation cycle counter, which are synchronized with each other on the basis of telecommunications messages, preferably serial telecommunications messages. In the invention all the inverter units take into memory the value of their own modulation counter at the termination time of a telecommunications message (Mes2), the master inverter unit sends the reading of its own counter in the following message to the other inverter units, and the other inverter units correct the reading notified by the master on the basis of the readings of their own modulation counters in the direction that makes the counters operate as simultaneously as possible.
