Abstract: The present invention discloses a safe operation method for voltage reduction arc suppression of a ground fault phase of a non-effective ground system, for use in ground fault safety operation of a neutral point non-effective ground generator or distribution network. When a single-phase ground fault occurs, an external voltage source is applied at a non-effective ground system side between a bus and the ground, or between a line and the ground, or between a neutral point and the ground, or between a shunting tap of a non-effective ground system side winding of a transformer and the ground, to reduce the fault phase voltage to be lower than the continuous burning voltage of a ground arc, thereby meeting the requirements of long-term non-stop safe operation. The operation means and control method effectively prevent power outages, and improve the reliability and security of power supply.

Abstract: A method for a selective detection of L-tryptophan (L-Trp) using formaldehyde as a medium is disclosed. The method includes preparation of a copper sulfide nanosheets-chitosan/acidified functionalized multi-wall carbon nanotubes (CuS NS—CS/F-MWCNTs) composite material, preparation of a composite film-modified electrode CuS NS—CS/F-MWCNTs/GCE, and a detection of the L-Trp. Since oxidation peaks of L-Trp and L-tyrosine (L-Tyr) overlap and are difficult to separate, the present invention provides a method for a highly selective detection of L-Trp through the Pictet-Spengler reaction of formaldehyde (HCHO) with L-Trp, in which the oxidation peak potential of L-Trp is shifted to 0.82 V and the oxidation peak potential of L-Tyr is 0.63 V, thereby effectively avoiding the interference of L-Tyr. The CuS NS—CS/F-MWCNTs/GCE is applied to detect L-Trp in the formaldehyde medium without any interference from L-Tyr or other amino acids with 50-fold concentrations.

Abstract: The present invention discloses an all-speed-range estimation method for a rotor position of a switched reluctance motor. Under a low-speed working condition, a sector is selected for triggering according to comparison between a current response value and a current threshold, so as to determine the rotor position of the motor; under a medium-speed working condition, the rotor position of the motor is determined, according to a change of the number of injected pulses with the motor speed, by querying a preset data table; under a high-speed working condition, a capacitor charging loop is designed since there is a small number of injected pulses; a response current formed by during injection of a pulse voltage charges a capacitor; the capacitor is detected to measure a voltage; and the rotor position is determined by querying a preset voltage-rotor position data table according to a voltage value.

Abstract: The present invention discloses a method for detecting compaction and shear strength characteristics of an asphalt mixture during construction compaction. The method mainly includes the following steps: using a device for detecting compaction and shear strength characteristics of the asphalt mixture; pressing a test claw into the asphalt mixture during construction; rotating the test claw slowly and uniformly to measure an internal temperature and a shear characteristic of the mixture during paving and subsequent compaction; calculating a corresponding compaction detection index based on the shear characteristic; and monitoring and guiding the construction quality and construction process accordingly based on the real-time detection index. The present invention measures the compaction detection index of the asphalt mixture during compaction simply, quickly and accurately. The present invention uses the compaction detection index together with a degree of compaction for dual control of asphalt pavement compaction.
