Simulation and Analysis of Induced Current of HV Parallel Reactor Disconnector for 500kV Double Circuit Line on the Same Tower

The 500 kV double circuit line with HV parallel reactors has a long outage time in ice melting operation.In this paper, we discussed the possibility of directly switching HV parallel reactor disconnector under the cold standby state,in order to further optimize the operation mode of DC ice melting line.We calculated the induced current of the HV parallel reactors disconnector in the 500kV LG A and B lines, and analyzed the related factors. We also calculate the overvoltage level of the HV parallel reactor disconnector, and put forward the parameter requirements, which provides reference for the type selection.

Study on the Influence Factors of Dry Hollow Parallel Reactor Loss

Reactor individual branch loss mutation is one of the important reasons leading to local temperature too high. In order to explore process deviation for dry type hollow shunt reactor loss amplification effect, this paper is establish a loss calculation model of dry-type air-core reactor as the tool, Comparative analysis relationship between the four common types of process deviation and the local branch loss. Calculation results show that the number of turns deviation are the main factor influencing the reactor partial loss, So the reactor production winding process should strengthen the control of the number of turns deviation.

From discovery to production: Scale-out of continuous flow meso reactors

A continuous flow parallel reactor system has been developed to provide a rapid and seamless transition from the discovery phase and production phase of chemical synthesis, particularly in low volume-high value pharmaceuticals production. Using a single fixed bed catalytic meso reactor, reactions can be screened on a small discovery scale over short time scales. The intensified process produces sufficient material for a full analysis. By replication of the single reactor in parallel, the same chemistry can be achieved on a larger scale, on a small footprint and without the mass and heat transport limitations of reactor scale-out in batch.
