About the PZK-560K
The PZK-560K is situated in the substation controls the opening and closing of the switch onto the line and monitoring the status of the bus switch. It comprises a PZK-56K (B / C or A) monitoring and control unit.
Key features
- Monitoring and control, including the identification of distribution line fault (including low current earth faults) their location, isolation and restoration of supply to unfaulted sections. It does not rely on a distribution network automation master (substation) control, as it can make decisions based on dynamic, distributed current differential protection, distributed remote tripping anti-islanding protection, distributed planning Island power supply imbalance
- Optional distribution transformer and reactive power compensation capacitor measurement and control functions.
- It can be flexibly configured to realise remote signalling, remote measurements and remotecontrol functionality.
- The use of voltage transformers or distribution transformers or dedicated power output as a power inputs, dual power automatically switches.
- Back-up power can be configured as needed to meet the requirements of AC power loss operation.
- Backup power optional maintenance-free lead-acid batteries, super capacitors or lithium batteries.
- Can be configured to use local and remote-control switches.
- With centralised and distributed installation.
- The distributed method allows several PZK-56A monitoring and control units to be installed in separate cubicles in the substation. One unit acts as the principal which communicates with a remote master station. It also communicates with the other units through a CAN bus network.
Technical Characteristics
- High-performance digital signal processor, large-scale field programmable logic array, with powerful real-time data processing
- Powerful memory resources to meet the needs of advanced application software and communications, system management, HMI and other functions
- Based on real-time Linux operating system, a hierarchical, modular software architecture, applications accessible through an open interface Ready-to-use, providing a unified support platform for a variety of smart distribution network applications.
- Provides a PC-like software development environment, allowing new applications to be easily opened and new application features to be added. Designed with hardware and software redundancy, with a strong fault tolerance and selfdiagnosis with a self-recovery capability.
- Communication based on the IEC 61850 standard design, with self-discovery, selfdescription function, realisation and distribution master plug and play.
- Easy to use HMI, with monitoring of operating conditions, site commissioning and easy maintenance.
- WEB service capabilities, allowing the use of a common web browser, access to real-time data, downloaded historical data and configuration files
