摘要:In the traditional domain of teleprotection signalling, there is a recognised triangle of performance. This triangle depends upon the required speed of communication, the expected dependability of the command, and the security of receipt. These three aspects are interlinked, and ...

摘要:The paper presents two strategies that enhance the voltage control of on-load tap changing transformers (OLTC). Simulation results demonstrate improvements in the voltage recovery times following a disturbance and that the schemes do not incur additional tap changes. These scheme...

摘要:The most effective method for demonstrating the performance of protection relay schemes is to test them using a power supply network. If this is not possible, the operation of real protection relays can be demonstrated using a specialist real time power system simulator. This pap...

摘要:The paper discusses a new technique which permits end to end channel schemes to be configured, without the need to purchase costly discrete carrier equipment. The relays connect directly to MODEM or multiplexed links, via an EIA RS232 interface on the rear of each relay in the sc...

摘要:Voltage control is a prime concern of distribution system operators and is critical to their ability to provide consumers with the quality of supply that they expect. The main technique for achieving voltage control on the network is on-load tap-change transformers. The enhanceme...
