摘要： To effectively prevent a micro arc causing damage to an apparatus and a substrate, by detecting a generation of the micro arc. A substrate processing apparatus is constituted so as to generate a plasma P, by applying a high frequency power to an electrode 210 provided in a processing chamber 200 from a high frequency power supply part 100 through a matching unit 300. A directional coupler 121 is provided between a high frequency power source 111 and the matching unit 300, so that a reflected wave reflected from the electrode 210 and a traveling wave advancing toward the electrode 210 are coupled to a detector 122. The detector 122 outputs a detection signal, when a level of a reflected wave Pr and a differential level thereof exceed each set value. In order to place an initial period of discharge out of a detection period, a delay traveling wave, which is a delayed traveling wave, is also outputted. A controller 130 determines the generation of a harmful micro arc, when coincidence of three detection signals outputted from the detector 122 is obtained, supplies an RF cut signal to a CPU 116, and temporarily stops or temporarily decreases a high frequency power from the high frequency power source 111.

摘要： A synchronous condenser is provided on an AC bus line which is connected to an AC power system via a circuit breaker. The AC bus line and a DC bus line are connected via a power converter system. In such a system, if three conditions: the breaker is opened; the synchronous condenser is under operation; and the power converter operates as an inverter, are met, the power converter is driven into a zero power factor operation, i.e., an operation to cancel a capacitive reactive power on the AC bus line including AC filters in order to prevent the synchronous condenser self-excitation.
