Patent EP-4280410-A1 (EP)
Inventor: LIU FANGCHENG
IPC: H02J3/00
Filed: 2023-05-18
Abstract: This application discloses an islanding detection method and apparatus. The method includes: An alternating current frequency of an inverter is monitored. The alternating current frequency fluctuates within a preset range when the inverter is in a normal control mode. When an instantaneous shifting value of the alternating current frequency exceeds the preset range, a frequency detected before instantaneous shifting is a first frequency. When a frequency in first frequency data within a first preset time period is greater than or less than only the first frequency, an alternating current frequency detected when the first preset time period ends is a second frequency. Output power of the inverter is continuously adjusted based on a change in the current alternating current frequency. When a frequency in second frequency data within a second preset time period is greater than or less than only the second frequency, it may be indicated in time that islanding occurs in the inverter, and an islanding status is reported. In the two-time determining manner, two situations of islanding occurrence and normal load switching are distinguished, to prevent the inverter from actively adjusting a system voltage or frequency, and improve accuracy of islanding detection.

Abstract: In a process for reducing the NOx contents in waste gases, particularly waste gases from a nitric acid plant, by catalytic reduction of the NOx gases, a solution is to be provided, by means of which especially the nitrogen oxides content in waste gases can be reduced to the low values now demanded, without the catalyst used being irreversibly poisoned. This is achieved by carrying out the reduction in two stages, part of the NOx gas being dissolved out in a first stage by means of alkalis such as, for example, sodium hydroxide solution or sodium carbonate solution, and the remainder of NOx gas then being catalytically reduced to nitrogen in a second stage with addition of ammonia.

Abstract: A process and circuit arrangement for exciting a solenoid coil to operate an iron core. Power from an AC power source (10) is full-wave rectified, and then allowed to flow to a solenoid coil (13) by a switch element (12) located between the full-wave rectification circuit (11) and the solenoid coil, which coil is made electrically conductive only for each short period of time corresponding to the top and its vicinities of the voltage wave-form of the rectified power so that the current is allowed to flow to the solenoid coil. Therefore, no current flows to the solenoid for each period of time corresponding to the trough and its vicinities of voltage wave-form of the rectified power. Thus, excitation and non-excitation of the solenoid is continuously alternated to give a dither effect to the iron core associated with the solenoid coil.
