Intelligent Capacitor Bank Control Many renewable energy resources, such as solar and wind, utilize dc to ac converters for electrical grid interconnections. During the dc to ac conversion, an inverter produces harmonics due to switching and nonideal power factor.
Figure 1 is an illustration of the capacitor bank control philosophy. The SEL-734 continuously monitors the bus voltage and load current to provide automatic control of two capacitor banks. When the bus voltage is above the voltage inhibit threshold and automatic control is enabled, the capacitor bank control logic is active.
In this paper, multi-channel capacitive sensor arrays based on mi-crostrip band-stop lters are studied. The sensor arrays can be used to detect the proximity of objects at di erent positions and directions. Each capacitive sensing structure in the array is connected to an in-ductive element to form resonance at di erent frequencies.
Capacitor controls are specifically engineered for the control of pole-mounted and pad-mounted switched capacitor banks in electric distribution systems. They benefit utilities by reducing unused capacity, regulating voltage, monitoring line conditions, and protecting capacitor banks.
In summary, we studied multi-channel capacitive sensor arrays based on multiple resonances. Each capacitive sensing structure in the array is connected to an inductive element to form a reso-nance at di erent frequencies.
Multiple capacitive sensors can be further integrated in a microstrip line and work as an array, with each element tuned to distinct resonant frequencies. This concept is similar to a microwave lter with tunable capacitance values [17, 18, 19].
