Blackouts severely impact the flow to modern society in many ways, from economic repercussions to life setbacks. It can be particularly damaging to enterprises such as hospitals, underground mining operations, gas stations, sewage treatment plants, etc. To solve the above problems, NR provides the unique stability control system to improve power system stability and significantly reduce possible blackouts.
Blackouts may seriously impact the daily life of modern society from economic sector to daily routine. Furthermore, power stability is particularly critical in important institutions, such as hospitals, underground mines, gas stations, sewage treatment plants, etc. NR Electric provides well-proven power stability control solutions to improve the power system’s stability and significantly reduce blackouts.The Power Stability Control System (PSCS) provides a system- level solution for the whole power grid. Different from other System Protection Schemes (SPS), the PSCS i…More Info
Power systems are required to remain stable after experiencing any disturbance, which may be caused by a fault, loss of a generator, or loss of a transmission line. Some disturbances may cause out-of-step between the interconnected systems, which may lead to blackouts and equipment damages if no remedial measures are taken to prevent this. In order to avoid these results, the PCS-993 out-of-step controller presents an effective way to prevent system collapse caused by out-of-step.When the out-of-step condition is detected, the PCS-993 controller will take corresponding actions to mai…More Info
PCS-994 is a frequency-voltage controller, which performs control functions for under-frequency, under-voltage, over-frequency and over-voltage. It can be used to perform load shedding in case of under-frequency or under-voltage conditions. It can also execute hydro-generator self-starting in a under-frequency scenario. Furthermore, it can conduct generator shut-down in case of over-frequency and system-separating in case of over-frequency or over-voltage conditions. The controller performs calculations and analysis based on the system’s voltage. Under-frequency load shedding and unde…More Info
PCS-994S frequency and voltage controller provides fast and selective generation shedding and load shedding due to a frequency or voltage abnormality in the power network, for avoiding the system crash and a large area blackout, maintaining the stability of the system voltage and frequency. With its flexibility and the powerful PCS-Studio configuration tool, PCS-994S offers future-oriented system solutions with high investment security and low operating costs.PCS-994S is applicable not only to conventional substations, but also to digital substations. It supports IEC 61850…More Info
