“…Distributed power generation is another name for distributed power sources in power systems. This power structure mainly refers to regional small grid power generation systems relative to large-scale power grids, and is generally limited to community-scale power generation systems [6][7]. In order to cope with the sharp reduction of global fossil energy and protect the increasingly fragile ecological environment, the global distributed power generation industry has developed rapidly with the support of various governments.…”

As the distributed generation (DG) is connected to the distribution network, the network structure of the original distribution network will change, and the original phase-to-phase (PTP) short circuit (SC) protection strategy will also change. At this time, the protection devices in the transmission line may make some incorrect action instructions, which will lead to the deviation of the coordination between the PTP protection devices in the distribution network and the instability of the system network structure. In order to ensure the reliability of transmission line power supply in distribution network and fully display the potential of DG, it is necessary to study the PTP short-circuit protection. This paper analyzes the influence of(TIO) DG on PTP short-circuit protection in distribution network from three aspects, that is, the influence of DG on PTP short-circuit protection before and after(BAA) access, and TIO DG on the reliability of PTP short-circuit protection. For the access of DG equipment, it changes the distribution of fault current in distribution system and brings transformation effect to the original distribution network protection configuration, so the PTP short-circuit equipment in distribution network will be affected. Finally, the method of combining automatic reclosing with PTP SC protection strategy of distribution network is proposed, so as to protect the safe operation of distribution network system.

“…At the same time, as the stacking order increases, the phase misalignment becomes more profound and causes the voltage swing not to add up in phase [1]. Moreover, the smaller base capacitance at higher stacked HBT leads to a more severe leakage current to the base that detrimentally impacts the output current phasor [27]. Therefore, stacking beyond four transistors does not indicate any output power improvement, as shown in Fig.…”

In this letter, we present the designs and development of a wideband, high output power quadruple-stacked heterojunction bipolar transistor (HBT) distributed amplifier (DA). In particular, the stacked HBT configuration can improve gain and output power while achieving a very wide bandwidth. To validate the proposed design concept, a quadruple-stacked HBT DA is designed in an indium phosphide (InP) process. The measurement results show an average gain of 16 dB from 7-115-GHz bandwidth with a maximum of 24-dBm saturated output power ( P sat ). To the best of the authors' knowledge, this is the first time quadruple-stacked HBT is used in a DA to achieve the highest output power compared with other published work in the same frequency range.

“…These active guiding structures are capable of signal amplification from DC up to their inductance-capacitance resonance frequency, called Bragg frequency. Distributed amplification techniques demonstrated broadband amplification up and above half of the process f max [11], [12], [13], [14], [15], [16]. Finally, with the amplifier being the basic block of transceivers, mixers and other key system parts can be derived from it.…”

This work presents a direct-conversion receiver for G-band applications formed by a cascaded single-stage distributed amplifier optimized for low noise, a single-balanced active mixer with inductive peaking and broadband RF matching, and a local oscillator (LO) driver. The receiver is optimized for reduced DC and LO power consumption, while practical levels of linearity and noise are retained. Prototypes of the complete receiver and of the stand-alone mixer are implemented in 0.62 mm 2 and 0.39 mm 2 of a 130 nm SiGe BiCMOS technology with 450 GHz maximum-oscillation frequency. The measured receiver saturated gain in LO compression is 17 dB with a 6 dB band of 60 GHz and a 3 dB band of 30 GHz, while the input power which compresses the gain by 1 dB (P in1dB ) is −35 dBm. The simulated receiver double-sideband noise figure is 11 dB. Finally, the circuit requires an LO power of −17 dBm at 170 GHz and a DC power of 98 mW. The measured gain of the mixer is −13 dB with a 3 dB band of 70 GHz. The component P in1dB is −20 dBm for −18 dBm LO power and 53 mW DC power. These circuits offer one of the largest operation bandwidth together with one of the lowest DC and LO power consumption against the state of the art.
