ABB offers three different permanent magnet technology solutions: Low speed, rugged, gearless system Medium speed, compact design High speed, small power plant In addition, we also provide the traditional synchronous wind turbine generator. ABB is committed to providing users with standard spare parts services for wind turbine generators. At the same time, we also opened an online spare parts procurement system for you. REU615 is a kind of special voltage protection measurement and control device, There are two standard configuration options available. Standard configuration A can be used in power and industrial distribution networks with distributed power supply Protection scheme based on voltage and frequency. Standard configuration B can be applied to automatic voltage regulation of a transber with a load regulating mechanism Application scheme. Two standard configuration scheme is also equipped with circuit breaker control, Measurement and condition monitoring. Standard configuration A Standard configuration B The 615 series protection measurement and control device is based on the IEC 61850 standard Development and design of the new platb. This makes the product from the root On the support of the device interoperability and horizontal communication, Without additional communication module. As long as the device is simply set according to the specific application, It can be directly put into use. 615 series protection measurement and control device to support a variety of communication protocols, Includes IEC 61850 (including GOOSE level communication), IEC 60870-5-103 and Modbus?. REU is the ABB Relion family of 615 Member of protection and control device product family Overvoltage and undervoltage protection relay REU 513 is connected to the protection transber PT side of the protection relay two. The device can continuously measure the fundamental frequency of the phase voltage of the protection b. Once a fault is detected, the relay will be configured according to the protection The function of b and to trip the circuit breaker, while providing alarm and fault recorder data. Overvoltage protection includes low fixed value U> and high fixed value section U>>, Under voltage protection includes low fixed value U< and high fixed value section U<<. The high value section of undervoltage protection can be set to calculate the positive sequence voltage. In addition, the high value of the undervoltage protection can be set to calculate only one Three phase voltages. Protection functions are independent of each other, have their own set of values and data records . The overvoltage and undervoltage function are measured by traditional voltage transber. The output contact matrix allows the start or trip signal of the protection section Connect to desired output contacts.
