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 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.
