Common use of Control Stability Clause in Contracts

Control Stability. Developer shall ensure that the Merchant Transmission Facility’s control performance is stable for all foreseeable AC system conditions, including any single or double contingencies on either the PJM or NYISO systems. Developer is responsible for determining the range of short-circuit capacities at the terminals, for any single or double contingency outages including failure of special protective systems. Developer shall ensure that harmonic instabilities, including core saturation instability, will not occur. Stable control performance shall be defined as adequately damped performance, free of persistent oscillations in real or reactive power into the Xxxx 00xx Xxxxxx 345kV Substation 345kV AC bus. In addition, stable control performance shall require that the Merchant Transmission Facility system shall not suffer repetitive commutation failures. If system conditions are found to create system control or harmonic instability in the Merchant Transmission Facility control system, including those reducing the short-circuit capacity below the calculated minimum post- contingency short-circuit capacity at the West 00xx Xxxxxx 345kV Substation 345kV AC bus, or the PSE&G Bergen 230kV AC bus, then adequate protective functions shall be included in the Merchant Transmission Facility system design to detect the instability and promptly trip the Merchant Transmission Facility system or take other effective corrective action.
