According to Wood Mackenzie, the installed capacity of photovoltaic systems installed globally will reach a record 270GW in 2023. By 2032, this growth rate will continue to accelerate to 330GW per year.   With the rapid development of the photovoltaic industry, power quality problems such as low PF power factor and unbalanced three-phase load due to the installation of photovoltaics continue to emerge.   YTPQC-SVG(Static Var Generator) can effectively solve the power quality problems caused by the installation of photovoltaics such as low PF power factor and unbalanced three-phase load.     YTPQC-ASVG Advanced Static Var Generator (ASVG) detects load current in real time through internal and external CT and analyzes the reactive current of load by TI DSP and FPGA, then generates PWM signal to IGBT inverter(3 Level) to generate inductive or capacitive current and compensate reactive current to realize the target power factor. YTPQC-ASVG can also compensate phase imbalance and harmonics. Compared with the traditional capacitor bank, YTPQC Advanced Static Var Generator has the advantages of fast response and high compensation accuracy without under-compensation or over-compensation problems, avoid resonance, etc.   Any technical questions, welcome contact us: [email protected]

With the increasing demand for electricity, the requirements for the distribution network are also getting higher and higher. It is not only necessary to ensure the reliability of power supply, but also to ensure the quality of power. However, in actual operation, due to various reasons, serious three-phase imbalance may occur in the distribution station area, threatening the safe and economical operation of the distribution network. Therefore, this paper expands the three-phase imbalance phenomenon in detail. The current AC power systems in the world are generally L1, L2, and L3 three-phase, and the three-phase current imbalance is caused by zero-sequence current and negative-sequence current.   Concept:   The positive sequence, negative sequence and zero sequence components of the power system are determined according to the order of the three phases of L1, L2, L3. Positive sequence: The L1 phase is 120 degrees ahead of the L2 phase, the L2 phase is 120 degrees ahead of the L3 phase, and the L3 phase is 120 degrees ahead of the L1 phase. Negative sequence: The L1 phase is 120 degrees behind the L2 phase, the L2 phase is 120 degrees behind the L3 phase, and the L3 phase is 120 degrees behind the L1 phase. Zero sequence: The three phases of L1L2L3 are the same, and neither phase is ahead nor behind.   Phenomenon:   If System is three-phase, three components above can be decomposed (a bit like the synthetic decomposition of forces, but in many cases one component has a value of zero) For an ideal power system, due to the three-phase symmetry, the values of both negative and zero sequence components are zero (this is also why we often say that there are only positive sequence components in normal cases) When the system fails, the three phases become asymmetric and can then be decomposed with magnitude negative and zero sequence components (sometimes only one) When there is a single-phase ground fault, the system has positive sequence, negative sequence and zero sequence components. When the two-phase short circuit fails, the system has positive and negative sequence components. When the two-phase short-circuit ground fault occurs, the system has positive sequence negative sequence and zero sequence components.   Application:   Recently YTPQC ASVG equipment was used in the Swiss Photovoltaic (PV) Project (Photovoltaic, energy storage, charging pile). The output of the on-site power system is 3-phase, but the load is one-phase, and the user wants to compensate for the three-phase imbalance. At the same time, only photovoltaic power supply, no mains power. At the same time, the on-site is a three-phase four-wire system. Note: A neutral line is required to compensate for the imbalance.   Power Quality Solution:   According the power quality analysis report, we calculated the unbalanced current that needs to be compensated on site through the on-site data. Combined with other governance requirements of users, the ...

CSE(YT) introduce new equipment for new energy production lines. ATE is a testing device used for functional testing of PCS (power control system) finished products. In the battery Energy Storage System(ESS), Battery, PCS, BMS are the most basic components. PCS is the core device in the battery energy storage system, which converts the electric energy stored by the battery into AC electric energy supply to the power grid or users. PCS is mainly composed of inverters, transformers, controllers, etc. Its main function is to convert direct current into AC power, control the input and output of power, and ensure the safety and stability of the system. PCS performance directly affects the operating efficiency and service life of the battery Energy Storage System.   Energy Storage System   The hybrid photovoltaic + energy storage system, that is, the direct current emitted by the photovoltaic module is stored in the battery pack through the controller, and the grid can also charge the battery through the two-way DC-AC converter. The energy collection point is at the DC battery end. During the day, photovoltaic power generation first supplies the load, and then charges the battery through the MPPT controller. The energy storage system is connected to the grid, and the excess electricity can be connected to the grid. At night, the battery discharge supplies the load, and the insufficient part is supplemented by the grid; When the power grid is outage, photovoltaic power generation and lithium batteries are only supplied to the off-grid load, and the grid-connected load cannot be used. When the load power is greater than the photovoltaic power generation, the grid and the photovoltaic can supply power to the load at the same time. Because photovoltaic power generation and load power consumption are not stable, it depends on the battery to balance the energy of the system. In addition, the system also supports users to set their own charging and discharging time to meet the needs of users.     ATE Test Equipment   ATE can perform more than 47 functional test items, including:   Low voltage start, communication test, correlation process determination, parameter writing, system time calibration, Pv voltage, current calibration, BAT voltage, current calibration, AC voltage, Current calibration, PFF value measurement limit, THDI measurement limit, DCI measurement efficiency, inverter efficiency, MPPT tracking, power factor adjustment, active and reactive power control, grid-connected recovery, grid-connected battery charging, battery discharge, battery voltage error determination, DRED function verification, in-plant operation data clearing, ISO protection verification, Groud Ⅰ Protection verification, product working status setting, test report generation, test data storage, etc. Which can ensure that all performance indicators of PCS equipment meet the standards and do high quality.     If any technical quiries about H...

In order to quickly respond to customer "urgent order", fast delivery, shorten the production cycle. YT Electric has began to introduce lean cell line. From the original flow production line to the lean cell line. The lead time of unit production is only one-fifth that of batch production. Product switching time is short, quick response, convenient communication, quick response. Great changes have taken place in production line layout, personnel training and raw material control. To realize this unit production line, we meet the following four requirements: 1. Short-term production; 2. Miniaturized equipment; 3. Continuous flow production for single-piece; 4. Multifunctional operator.     Benefits of lean unit production line: 1. Reduce costly handling and waiting in the production process; 2. Shorten the product delivery time, which will meet the needs of customers and make the company's investment in the product return as soon as possible; 3. Save factory space so that it can be used for other added value purposes; 4.
