Remote acquisition of insulator icing flashover signal based on frequency optimization of ring-shaped intelligent current sensor

In order to improve the safety of power grid operation and avoid the hidden danger in the process of power supply, a remote acquisition method of insulator ice-covered flashover signal based on the frequency optimization of ring intelligent current sensor was proposed. According to principle of take electricity by capacitance, transmission line, current sensor, current sensor B and double rectifier circuit composed of parallel resonant magnetic circuit for electric model. By monitoring the current sensor and current sensor B the secondary side of induction electromotive force, magnetic core KaiQi gap equivalent permeability values, such as through the calculation of current sensor parameters of iron core and coil number of turns. In this paper, the current sensor is optimized to improve the power monitoring effect, and the remote acquisition of the flashover signal of insulator icing is realized. The experimental results show that. This monitoring method can effectively monitor the maximum load power, load resistance and load voltage of the model when the current value is different. In the face of impedance branch resonant, resonant and open air gap and other circumstances, can effectively monitor the power taking situation, a wide range of applications.

Total Unduplicated Reach and Frequency Optimization at Procter & Gamble

The Procter & Gamble Company (P&G) is a consumer goods corporation that employs over 90,000 people and has operations in roughly 80 countries worldwide. Products in P&G’s 10-category portfolio of products are sold in over 180 countries. The Consumer Research Analytics group at P&G empowers internal clients by using analytics to ensure that the products in P&G’s portfolio of products are not just well received by consumers but become the products of choice for the maximum number of consumers, thereby maximizing P&G’s market share. One of the most frequently used analytical approaches for managing a product line is Total Unduplicated Reach and Frequency analysis. We replaced the previous enumerative approach with integer programming coupled with cuts to the unit hypercube to dramatically speed up the analysis. As a result, P&G achieved higher utilization of its system, improvements to existing products, and more thorough analyses for product line planning and other applications.
