3 Protection and ontrol Modern power systems are under increasing constraints in their ability to transmit power from generation facilities to major load centers, and are forced to operate closer to their natural stability limits. Under these conditions, the critical clearing angle and corresponding critical clearing time become progressively smaller and there is an increasing need to minimize the fault clearing time on these constrained circuits. The 90Plus is ideally suited for application on circuits where fast fault detection and small breaker failure margin are required. The 90Plus allows transmission limits to be maintained or even increased while respecting the transient stability limits of the power system. 90 Plus Sub-cycle istance Protection The 90Plus sub-cycle distance algorithm employs a combination of energy-based integrator/comparators and high-speed phase comparators to determine if a fault is internal or external. The energy integrator algorithm uses both the magnitude of the operating and polarizing signals as well as the relative phase information to provide fast, secure operation for obvious internal faults. The high-speed phase comparators examine the angular relationship between operating and polarizing signals independent of magnitude to provide greater security in the presence of VT transients. For faults with low SIR or close-in high magnitude faults, the 90 Plus can provide trip times under ½ cycle for phase-phase faults and between ½ to ¾ of a cycle for ground faults. apacitive oupled Voltage Transformer Transient Filter Transients generated by apacitive oupled Voltage Transformers (VT) tend to have relatively significant magnitudes and long durations. The impact of these transients is particularly pronounced when protecting transmission lines where the Source Impedance Ratio (SIR), the ratio between the system equivalent impedance and the relay reach impedance, is large. The voltage signals are crucial for proper operation of a distance element, but become significantly distorted by transient components that are generated but the VT. This presents a significant challenge particularly for fast impedance protection algorithms. Generally, VT transients will cause the magnitude of the voltage signal to be underestimated, causing distance elements to overreach.

4 detect VT transients under high SIR and incorporate an intentional operating delay on the distance elements to ridethrough the period with VT transients. ynamically reducing the reach of the distance elements to prevent them from overreaching is another strategy to cope with VT transients. The 90Plus introduces a true digital filter into the voltage signal path that removes distortions generated by the VT, resulting in a signal that is a more accurate reproduction of the power system voltage. The 90Plus is then able to provide sub-cycle distance protection in the presence of VT transients, without adding intentional delays or reducing fault coverage. The 90Plus sub-cycle distance algorithm is secure and sufficiently fast for a wide range of power system scenarios. The VT filter increases the speed of operation of the 90Plus for an even wider range of contingencies. ustom Prograable Logic esigner 90 Plus user prograable protection logic and independent automation logic allows the users to build custom protection and automation schemes. s with all filters, the 90Plus VT filter needs to be tuned to a specific application, so that the behaviour of the VT is characterized and reduced to 3 critical parameters that become settings for the relay. VT Transient for Fault at Voltage Maximum and orrected Voltage Signal VT Transient for Fault at Voltage Zero-crossing and orrected Voltage Signal Fast Breaker Failure Reset With stability limits shrinking, the ability to achieve fast breaker failure resetting times becomes more challenging to achieve. When the total worst-case clearing time including breaker failure starts to approach cycles, often there is little more than 1 cycle margin left to allow for breaker failure protections to reset. The 90Plus provides fully independent breaker failure protection for breakerand-a-half or ring bus arrangements with consistent sub-cycle resetting times (5/8 of a power system cycle), allowing for shorter critical clearing times and increased line loading. ven with T saturation, current reversal and severe subsidence, the URPlus breaker failure element provides secure, dependable protection with consistent subcycle reset times In-Zone transformer ompensation Phase distance elements in the 90 Plus can be used to detect faults through different types of three-phase wye/ delta transformers, allowing application of the 90 Plus for backup protection at generating stations, VTs and Ts can be installed independently of each other on either side of the power transformer. The relay automatically compensates for transformer connections for accurate far-reaching stepped distance backup protection schemes Series-ompensated Lines The 90 Plus provides enhanced stability and security by employing an adaptive distance reach control to cope with the overreaching and sub-synchronous oscillations when applied to, or in the vicinity of, series compensated lines. epending on the needs of the application, the relay can be prograed to dynamically be self-polarized or use memory voltage for polarization for additional security. Single-Pole Tripping The 90 Plus relay uses a highly secure and dependable phase selection algorithm that provides fast and accurate fault type identification. convenient trip function is built-in to coordinate actions of the key protection and teleprotection operands in single-pole tripping applications
