Wang Zhiyong: Do A Good Job In Wind Power Business.

Working six and a half days a week, working until 9 pm every day, but still being overwhelmed by the endless orders.

This is the worry of Wang Zhiyong's happiness: "if we want to receive more orders, we will collapse."

Collapse? Obviously, by comparison, Wang Zhiyong is closer to pride.

"Although China is a big country in wind power equipment manufacturing, there are few technologies that can lead the world, and we have to count one."

Wang Zhiyong, who was wearing a blue work cloth, kept a gentle tone of voice, even when he said such a brave word.

Wang Zhiyong's "Engineering Male" identity is easy to lock up.

Wang Zhiyong and his three de Prat have been stealthy.

This is not only because of his personal attitude, but also because he has done too professionally.

If it weren't for the right time to catch up with the outbreak of China's wind power, maybe three of Pu Hua still had a longer incubation period.

Three de Pu Hua, the world's leading manufacturer of MCR type dynamic reactive power compensation equipment.

It is obvious that stories should be abstracted from reactive power compensation.

In our power supply system, there are not only the active power to maintain the daily power consumption of electric lights, computers, household appliances, but also a kind of energy that is not known to ordinary people: reactive power.

It is to establish and maintain the electric power of magnetic field in electrical equipment.

Any power equipment that needs to rely on electromagnetic field to maintain operation needs to consume reactive power.

In the power system, the high reactive power will reduce the efficiency of sending active power, but the low reactive power will cause the voltage drop, deteriorate the power grid environment, and even lead to the collapse of the power grid.

As the generator belongs to the electromagnetic equipment, it can absorb and consume reactive power in the power grid at any time. Therefore, timely and proper replenish of reactive power is an important link to maintain the stable operation of the power grid.

Reactive power compensation equipment is born, and it is in an indispensable position in the power supply system.

In the era of unified fire and hydropower generation, due to the highly controllable power generation process, the performance requirements of the power grid for reactive power compensation equipment are not strict.

But the rise of wind power has changed the status of reactive power compensator.

Because the wind hour is large and the time is sometimes absent, the operation of the wind turbine is also in an uncontrollable state, and its consumption of reactive power in the grid varies correspondingly.

With the increasing proportion of wind power in the power grid, the dynamic and timely compensation of reactive power in the power grid has become a key link to maintain the stability of the power grid.

Dynamic var compensator, which is the business of three De Hua Hua.

"If there is no wind power, our company will not develop so fast."

Wang Zhiyong said.

The graduate of Electrical Engineering Department of Tsinghua University started business in 2003, and wind power was not hot at that time. His initial research and development didn't point to wind power.

"Metallurgical, electrified railways, petrochemical and so on, these large-scale electricity consumption, load has certain volatility, and there are still some areas of harmonic pollution can be used."

In 2005, Wang Zhiyong came into contact with Jin Feng Technology in an accidental opportunity.

At that time, Jin Feng was looking for the dynamic reactive power compensation equipment used in the wind turbines for his 750kW model. They saw the technology of the three De Hua Hua at the moment, and the two parties soon reached a cooperation agreement.

Three de Pu Hua has entered the field of wind power, and has entered a period of rapid growth.

The product that lets Jin Feng Technology love at first sight is called MCR SVC.

There are two professional terms that can not be broken.

SVC is a dominant dynamic reactive power compensation equipment.

MCR is the abbreviation of magnetically controlled reactor.

Three the success of de Pu Hua lies in the first place in the world to achieve the efficient combination of the two.

The principle of MCR comes from the Soviet Union, but because of its slow response speed, it has never been used in the field of SVC.

Even two years ago, it is impossible for famous scholars in China to demonstrate the high speed response of MCR by writing argumentation.

What the experts don't know is that this impossible task has been completed by Wang Zhiyong's team in 2004.

In 2004, three De Hua reduced the response time of MCR SVC from a few hundred milliseconds to 20 milliseconds.

Until today, this record of three is still far ahead of the competitors.

"As far as we know, the products of other manufacturers are also faster than 100 milliseconds."

Wang Zhiyong said proudly.

"It is really not easy to combine these two technologies. It really needs some special technical means.

Many are not done in the laboratory. "

Wang Zhiyong understood the outdated conclusions of experts.

It is these special means that constitute the unique competitive barrier of three De Hua Hua.

"We combine the most advanced power electronics technology with MCR to achieve a fundamental breakthrough in technical performance.

We have made it all over the world! "

But MCR is not a SVC wandering person.

Traditional TCR technology still occupies half of the market.

But compared with TCR, Wang Zhiyong believes that MCR technology as a latecomer has obvious advantages, especially in the field of wind power.

First of all, MCR SVC can run steadily for 30 years and basically needs no maintenance.

TCR SVC often needs to be overhauled after running for 5 to 6 years.

For the wind farms which are mostly remote and difficult to maintain, the advantage of MCR is almost overwhelming.

Another important advantage of MCR is that it can run steadily in extreme climates and weather conditions.

In the winter of 40 degrees below the surface wind farms, the high wind and salt fog weather of offshore wind farms can not be MCR, and TCR is much more delicate than that of the wind farms.

MCR is not only superior to its predecessors in performance, but also more than 10% lower in price than TCR.

So in just two years, the growth of MCR is far beyond imagination.

Meanwhile, three De Hua Hua relies on a unique fast response speed and occupies half of the market share of the MCR SVC market.

Obviously, this figure is not surprising compared with the industry position and leading edge of three De Hua Hua.

But in the complex and special market of electricity, this has already manifested the strength of three Pu Hua.

"Since the opening of the wind power market, our performance has doubled at least once a year, of which wind power contracts account for about 80% of the total contract."

In 2009, three De Hua achieved sales revenue of 110 million yuan, of which 86 million yuan was wind power.

In Wang Zhiyong's view, the market is becoming more and more conducive to its own development.

In 2009, the national Power Grid Corp issued regulations requiring all wind farms to be equipped with reactive power compensation equipment.

In the past two years, the demand for reactive power compensation equipment in wind farms also reflects the trend of rapid increase in installed capacity and large-scale equipment.

Two years ago, most of the wind farms were only equipped with SVC of 10% of the installed capacity. Now 30% of the cases have been reported, and 50% of the rumors recently began to spread around rivers and lakes.

"The larger the installed capacity and the larger the equipment, the more prudent the owners will be when selecting the equipment suppliers. The more advantageous the enterprises with obvious advantages to the three De Hua" will be.

Wang Zhiyong said.

In 2009, three De Hua Hua won the SVC matching contract of Gansu's 10 million kilowatt wind power base with obvious advantages. At the same time, it received a 3600 kilo single unit order, which will be the largest dynamic reactive power compensator in China's wind farm so far.

For the three De Hua Hua, there was another landmark order in 2009: supporting SVC for an electric arc furnace in an iron and steel enterprise.

It means that three de Prof will challenge the response speed of 10 milliseconds.

If successful, this will further consolidate its technological dominance.

In the meantime, for Wang Zhiyong, the same urgent task as completing orders is to build new capacity and expand new products.

In the ascendant wind power investment and the rapid pformation of the power industry, the three best days of the city have just begun.
