Better than expected: PR pf this project is 3.8% higher than initial simulation
Kazakhstan gets 2200-3000 sun hours annually, bringing great potential for PV development. The 50 MV PV plant, backed by the investor Risen Energy, is a special plant among the 37 PV plants currently in Kazakhstan, located in Chulakkurgan, Туркестан. There, the wind howls, the sand is heavy, and the climate is harsh. Data from the weather station that shows the lowest recorded temperature is -27°C and is the highest 42°C. Nevertheless, the actual performance ratio (PR) measurement result of the plant у јулу је 80.39%, which is 3.8% виши од симулиране вредности. У потрази за екстремно средине, енергетске приноса well exceeded design and return on investment (РОИ) expectations, despite the шансе being stacked against it.
Onsite тестови were performed according to ИЕЦ 61724: праћење перформанси фотонапонског система. The test result is as follows:
As shown, the all-time highest actual PR да 82.44%, and the 7-day weighted average да 80.39%. According to the PV system report submitted to the supervisor for review, the simulated PR for July what 76.6%. The actual PR is 3.8% higher than simulated.
Како did this PV планира exceed expectations тако dramatically? Пројекат користи Рисен Енерги 330 В полицристаллине ПВ модуле, Хуавеи СУН2000-185КТЛ стринг инвертерс, and Арцтецх Солар Скилине 1В84 Трацкерс. The string inverters work with the trackers, and the PV modules move by tracking the sun, ensuring the optimal status of each PV string in the plant. The project owner had great things to say about Huawei's string inverters for their outstanding performance in ensuring the efficient and reliable operation of the plant.
Huawei inverter's multi-MPPT feature can help minimize the impact of PV string mismatch during dusty and cloudy weather. A 3.5 МВ ПВ арраи Суппортс 170 МППТ Роутес то ensure that each PV string works at its optimum, which in turn brings higher energy yields. Not only this, but Huawei SUN2000 series string inverters can operate over a wide temperature range, which is befitting to environments with both extremes of hot and cold such as Kazakhstan. They can run stably in the temperature range of -40°C to 60°C, with the availability reaching over 99.996%. Ekstremno hot or cold conditions would usually Посе severe challenges on components. Huawei employs high component selection standard and patented heat dissipation technologies to ensure the reliability of all components, чак иу difficult или severe environments.
In addition, Huawei string inverters use low power consumption control technology, power supply technology with a wide input voltage range, and power component shutdown peak suppression technology. Дакле, они подржавају опсег радног напона као широк као 500-1500 в. a lower operating voltage lower limit enables inverters to start early and shut down late every day, which allows them to generate more electricity.
The success of this project is inseparable from the meticulous design and optimization of Risen energy's Overseas Project Technical Team based in China. Јефф ЛВ, ЦТО, were on site personally for inspection and research. Under his guidance, the technical team of Risen Energy compares more than 100 system design solutions with automatic configuration loss and algorithms, and analyzes the cost and benefit sensitivity. The team optimizes and selects the cost structure of each project. The modular, powerful, and capable solution design ensures a balance in project cost and quality. The corresponding balance created between cost and energy yield is the key to the high energy yield of the project.
According to data from the Ministry of Energy of Kazakhstan, in the first quarter of 2020, the country generated 548.4 million kWh of electricity using renewable energy, 35.7% of it generated from PV. In the Concept of Transition towards Green Economy, the Kazakhstan government proposed to increase the proportion of electricity generated from renewable energy to 3% by 2020. We believe that more ПВ plants with unexpected ПР will make the future of Kazakhstan's ПВ маркет landscape brighter.
