a. Type 1a: In this scheme, one or more samples of the product are subjected to the determination activities. A certificate of conformity or other statement of conformity (e.g. a letter) is issued for the product type, the characteristics of which are detailed in the certificate or a document referred to in the certificate. Subsequent production items are not covered by the certification body’s attestation of conformity. The samples are representative of subsequent production items which could be referred to by the manufacturer as being manufactured in accordance with the

Subsequent production items are not covered by the certification body’s attestation of conformity. The samples are representative of subsequent production items which could be referred to by the manufacturer as being manufactured in accordance with the certified type. The certification body may grant to the manufacturer the right to use the type certificate or other statement of conformity (e.g. letter) as a basis for the manufacturer to declare that subsequent production items conform to the specified requirements. b. Type 5: The surveillance part of this scheme allows for the choice between periodically taking samples of the product either from the point of production, or from the market, or from both, and subjecting them to determination activities to check that items produced subsequent to the initial attestation fulfill the specified requirements. The surveillance includes periodic assessment of the production process, or audit of the management system, or both.

P

anticipated grid faults, including: P • Single phase to ground fault (any phase) P • Two phase isolated fault, between any two phases P • Two phase grounded fault, involving any two phases P • Three phase short-circuit fault. P A full discussion of these faults and the resulting impact on voltage magnitude and phase angles is included in Annex A. P The short circuit emulator and grid simulator described in 4.3.3 and 4.3.4 are informative examples and are not intended to restrict design flexibility. Other designs may be used to achieve equivalent test functionality. The grid simulator used to achieve test of 4.3.4. P 4.2 Test circuit P The LVRT test circuit includes a DC source, the EUT, a grid fault simulator and the grid. A PV simulator (or PV array) provides input energy for the EUT. The output of the EUT is connected to the grid via a grid fault simulator, as shown in Figure 1.

PV array simulator and the grid simulator used in the LVRT test circuit. P 4.3 Test equipment P 4.3.1 Measuring instruments P Waveforms shall be measured by a device with memory function, for example, a storage or digital oscilloscope, or a high speed data acquisition device. Accuracy of the oscilloscope or data acquisition system should be at least 0.2% of full scale.

TRF No. IEC TS 62910_V2.0

Voltage transducers (or voltage transformers) and current transducers (or current transformers) are the required sensors for measurement. The accuracy of the transducers should be 0.5 % of full scale or better. It is necessary to select the transducer measuring range depending on the normal value of the signal to be measured. The selected measuring range shall not exceed 150 % of the normal value of the measured signal. The transducer accuracy requirements are shown in Table 1

P 4.3.2 DC source P A PV array, PV array simulator or controlled DC source with PV characteristics may be used as the DC power source to supply input energy for the LVRT test. As the EUT input source, the DC power source shall be capable of supplying the EUT maximum input power and other power levels during the test, at minimum and maximum input operating voltages of the EUT. PV array simulator used as the DC power source to supply input energy. P The PV simulator should emulate the current/voltage characteristic of the PV module or PV array for which the EUT is designed. The response time of a PV simulator should not be longer than the MPP tracking response time of EUT. P For a EUT under test without galvanic isolation between the DC side and AC side, the output of the PV simulator shall not be earthed. P The equivalent capacitance between the output of the PV simulator and earth should be as low as possible in order to minimize the impact on the EUT. P A PV array used as the EUT input source shall be capable of matching the EUT input power levels specified by the test conditions. It is necessary to select a period of time in which the solar irradiance is stable and does not vary by more than 5 % during the test. P
