1.introduction

More than 2,000 years ago, Zhang Qian traveled to the Western regions to open up the Silk Road, which opened the door of trade between the East and the West. Nowadays, with the deepening of the Belt and Road Initiative, more and more Chinese enterprises are riding the wave of "going out" and are active on the international stage.
The Belt and Road Initiative aims to promote economic cooperation and connectivity among countries along the routes, involving a number of industries and sectors, including industrial automation. Many Chinese inverter brands are deeply engaged in the "Belt and Road", which has broad market opportunities and development space.

FGI actively responds to the national "Belt and Road" initiative, fully exchanges and cooperates with large enterprises, and has operations in more than 40 countries and regions around the world. By providing high-quality products, localized services, technical support and cooperation opportunities, it has achieved certain success in the field of industrial automation in countries along the route.

2. Project overview

In a sugar factory in Pakistan, in order to change the backward situation of using cattle to pull sugar pressing mechanism, China assisted the construction of "Iron Pakistan" complete set of press equipment to process sugar. After understanding the needs of the customer, FGI provided the customer with a solution to meet the requirements of the customer's field, with a special medium voltage inverter produced by FGI. Now in continuous use for several months, customers have been very satisfied with the results after using the FGI inverter and have sent photos of the site to our staff.

 3.Application condition

In the process of sugar production, the extraction rate is an important index affecting the total yield of sugar. If the extraction rate is increased by 1%, the total recovery rate is increased by 0.88% ~ 0.92%. There are many factors affecting the extraction rate:

Due to the unadjustable speed of the press, the thickness of the cane layer transported from the ripping machine will not meet the requirements for about 10% of the time, which will make the average extraction rate of cane juice less than 95.4%.

The lower the extraction rate, the greater the loss of sugarcane juice, resulting in lower yield and low economic benefit.

If the speed of the press can be adjusted, when the thickness of the cane layer is not enough, the speed of the press motor can be reduced to make the cane layer reach the normal thickness before pressing. This press will be more adequate, and the average extraction rate will be increased by more than 0.2%. At the same time, due to the reduction of speed, the current is reduced, so as to achieve the purpose of energy saving and power saving.

FGI provides two FD5000S series medium voltage drive combined with the user's field conditions, which solves the problem of speed regulation of the press.

3.Use energy efficiency

After the operation of FGI FD5000S series medium voltage drive, after repeated testing, the operation parameters have been normal, safe and reliable, and the indicators meet the field requirements.

When the cane layer is thinner, by reducing the speed of the press motor, the speed is reduced, the power consumption is reduced, and the purpose of energy saving is achieved.

The soft start and soft stop of the motor are implemented to optimize the field process and improve the production efficiency.
Since the FGI inverter has capacitors as energy storage components, it can improve the power factor of the grid side and improve the quality of the power grid.
The influence of harmonics on the power grid is suppressed, the impact of surge voltage on the inverter bridge is improved, and the reliability of the whole system is improved.
The extraction rate of sugarcane juice is improved, the sugar yield of each pressing season is increased, and the economic benefit of enterprises is greatly increased.

FGI hopes to meet the industrial automation needs of countries along the Belt and Road by providing high-quality, reliable performance products. It is expected to continue to provide high-value comprehensive solutions in the field of national development and energy conservation in the future, and help build high-quality development of the "Belt and Road".
